CERT/CC Vulnerability Note VU#479268

Overview

The Apache HTTP server contains a denial-of-service vulnerability that allows remote attackers to to conduct denial-of-service attacks on the HTTP basic authentication module of an affected server.

Description

The Apache HTTP server contains a denial-of-service vulnerability in the apr_password_validate() function. The Apache Software Foundation has provided the following description of this vulnerability:

Apache 2.0 versions 2.0.40 through 2.0.45 on Unix platforms were vulnerable to a denial-of-service attack on the basic authentication module, which was reported by John Hughes <john.hughes@entegrity.com>. A bug in the configuration scripts caused the apr_password_validate() function to be thread-unsafe on platforms with crypt_r(), including AIX and Linux. All versions of Apache 2.0 have this thread-safety problem on platforms with no crypt_r() and no thread-safe crypt(), such as Mac OS X and possibly others. When using a threaded MPM (which is not the default on these platforms), this allows remote attackers to create a denial of service which causes valid usernames and passwords for Basic Authentication to fail until Apache is restarted. We do not believe this bug could allow unauthorized users to gain access to protected resources.

For further information, please read the announcement located at

http://www.apache.org/dist/httpd/Announcement2.html

Impact

This vulnerability allows remote attackers to conduct denial-of-service attacks on the HTTP basic authentication module of an affected server.

Solution

The Apache Software Foundation recommends that users upgrade to version 2.0.46 to address this vulnerability. The latest version of Apache is available at:

Apache 2.0.46 Released
The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the ninth public release of the Apache 2.0 HTTP Server. This Announcement notes the significant changes in 2.0.46 as compared to 2.0.45.

This version of Apache is principally a security and bug fix release. A summary of the bug fixes is given at the end of this document. Of particular note is that 2.0.46 addresses two security vulnerabilities:

Apache 2.0 versions 2.0.37 through 2.0.45 can be caused to crash in certain circumstances. This can be triggered remotely through mod_dav and possibly other mechanisms. The crash was originally reported by David Endler <DEndler@iDefense.com> and was researched and fixed by Joe Orton <jorton@redhat.com>. Specific details and an analysis of the crash will be published Friday, May 30. No more specific information is disclosed at this time, but all Apache 2.0 users are encouraged to upgrade now. [http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0245]

Apache 2.0 versions 2.0.40 through 2.0.45 on Unix platforms were vulnerable to a denial-of-service attack on the basic authentication module, which was reported by John Hughes <john.hughes@entegrity.com>. A bug in the configuration scripts caused the apr_password_validate() function to be thread-unsafe on platforms with crypt_r(), including AIX and Linux. All versions of Apache 2.0 have this thread-safety problem on platforms with no crypt_r() and no thread-safe crypt(), such as Mac OS X and possibly others. When using a threaded MPM (which is not the default on these platforms), this allows remote attackers to create a denial of service which causes valid usernames and passwords for Basic Authentication to fail until Apache is restarted. We do not believe this bug could allow unauthorized users to gain access to protected resources. [http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0189]

The Apache Software Foundation would like to thank David Endler and John Hughes for the responsible reporting of these issues.

This release is compatible with modules compiled for 2.0.42 and later versions. We consider this release to be the best version of Apache available and encourage users of all prior versions to upgrade.

Apache 2.0.46 is available for download from
http://httpd.apache.org/download.cgi
Please see the CHANGES_2.0 file, linked from the above page, for a full list of changes.

Apache 2.0 offers numerous enhancements, improvements, and performance boosts over the 1.3 codebase. For an overview of new features introduced after 1.3 please see

http://httpd.apache.org/docs-2.0/new_features_2_0.html
When upgrading or installing this version of Apache, please keep in mind the following:

If you intend to use Apache with one of the threaded MPMs, you must ensure that the modules (and the libraries they depend on) that you will be using are thread-safe. Please contact the vendors of these modules to obtain this information.

Apache 2.0.46 Major changes
Security vulnerabilities closed since Apache 2.0.45
*) SECURITY [CAN-2003-0245]: Fixed a bug that could be triggered remotely through mod_dav and possibly other mechanisms, causing an Apache child process to crash. The crash was first reported by David Endler <DEndler@iDefense.com> and was researched and fixed by Joe Orton <jorton@redhat.com>. Details will be released on 30 May 2003.

*) SECURITY [CAN-2003-0189]: Fixed a denial-of-service vulnerability affecting basic authentication on Unix platforms related to thread-safety in apr_password_validate(). The problem was reported by John Hughes <john.hughes@entegrity.com>

Bugs fixed and features added since Apache 2.0.45
*) Fix for mod_dav. Call the 'can_be_activity' callback, if provided, when a MKACTIVITY request comes in. [Ben Collins-Sussman <sussman@collab.net>]

*) Perform run-time query in apxs for apr and apr-util's includes. [Justin Erenkrantz]

*) run libtool from the apr install directory (in case that is different from the apache install directory) [Jeff Trawick]

*) configure.in: Play nice with libtool-1.5. [Wilfredo Sanchez]
*) If mod_mime_magic does not know the content-type, do not attempt to guess. PR 16908. [Andrew Gapon <agapon@telcordia.com>]

*) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session caching. PR 17864. [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]

*) Add a delete flag to htpasswd. [Thom May]

*) Fix mod_rewrite's handling of absolute URIs. The escaping routines now work scheme dependent and the query string will only be appended if supported by the particular scheme. [André Malo]

*) Add another check for already compressed content in mod_deflate. PR 19913. [Tsuyoshi SASAMOTO <nazonazo@super.win.ne.jp>]

*) Fixes for VPATH builds; copying special.mk and any future .mk files from the source tree as well as the build tree (now creates a usable configuration for apxs), and eliminated redundant -I'nclude paths. [William Rowe]

*) Code fixes, constness corrections and ssl_toolkit_compat.h updates for SSLC and OpenSSL toolkit compatibility. Still work remains to be done to cripple features based on the limitations of RSA's binary distribution of their SSL-C toolkit. [William Rowe, Madhusudan Mathihalli, Jeff Trawick]

*) Linux 2.4+: If Apache is started as root and you code CoreDumpDirectory, coredumps are enabled via the prctl() syscall. [Greg Ames]

*) ap_get_mime_headers_core: allocate space for the trailing null when folding is in effect. PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]

*) Fix --enable-mods-shared=most and other variants. [Aaron Bannert]
*) mod_log_config: Add the ability to log the id of the thread processing the request via new %P formats. [Jeff Trawick]

*) Use appropriate language codes for Czech (cs) and Traditional Chinese (zh-tw) in default config files. PR 9427. [André Malo]

*) mod_auth_ldap: Use generic whitespace character class when parsing "require" directives, instead of literal spaces only. PR 17135. [André Malo]

*) Hook mod_rewrite's type checker before mod_mime's one. That way the RewriteRule [T=...] Flag should work as expected now. PR 19626. [André Malo]

*) htpasswd: Check the processed file on validity. If a line is not empty and not a comment, it must contain at least one colon. Otherwise exit with error code 7. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>, Thom May]

*) Fix a problem that caused httpd to be linked with incorrect flags on some platforms when mod_so was enabled by default, breaking DSOs on AIX. PR 19012 [Jeff Trawick]

*) By default, use the same CC and CPP with which APR was built. The user can override with CC and CPP environment variables. [Jeff Trawick]

*) Fix ap_construct_url() so that it surrounds IPv6 literal address strings with []. This fixes certain types of redirection. PR 19207. [Jeff Trawick]

*) forward port of buffer overflow fixes for htdigest. [Thom May]
*) Added AllowEncodedSlashes directive to permit control of whether the server will accept encoded slashes ('%2f') in the URI path. Default condition is off (the historical behaviour). This permits environments in which the path-info needs to contain encoded slashes. PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]

*) When using Redirect in directory context, append requested query string if there's no one supplied by configuration. PR 10961. [André Malo]

*) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise the pattern will not always match as desired. PR 12596. [André Malo]

*) mod_autoindex now emits and accepts modern query string parameter delimiters (;). Thus column headers no longer contain unescaped ampersands. PR 10880 [André Malo]

*) Enable ap_sock_disable_nagle for Windows. This along with the addition of APR_TCP_NODELAY_INHERITED to apr.hw will cause Nagle to be disabled for Windows. [Allan Edwards]

*) Correct a mis-correlation between mpm_common.c and mpm_common.h; This patch reverts us to pre-2.0.46 behavior, using the ap_sock_disable_nagle noop macro, because ap_sock_disable_nagle was never compiled on Win32. [Allan Edwards, William Rowe]

*) Fix a build problem with passing unsupported --enable-layout args to apr and apr-util. This broke binbuild.sh as well as user-specified layout parameters. PR 18649 [Justin Erenkrantz, Jeff Trawick]

*) If a Date response header was already set in the headers array, this value was ignored in favour of the current time. This meant that Date headers on proxied requests where rewritten when they should not have been. PR: 14376 [Graham Leggett]

*) Add code to buildconf that produces an httpd.spec file from httpd.spec.in, using build/get-version.sh from APR. [Graham Leggett]

*) Fixed a segfault when multiple ProxyBlock directives were used. PR: 19023 [Sami Tikka <sami.tikka@f-secure.com>]

*) SECURITY [CAN-2003-0134] OS2: Fix a Denial of Service vulnerability identified and reported by Robert Howard <rihoward@rawbw.com> that where device names faulted the running OS2 worker process. The fix is actually in APR 0.9.4. [Brian Havard]

*) Forward port: Escape special characters (especially control characters) in mod_log_config to make a clear distinction between client-supplied strings (with special characters) and server-side strings. This was already introduced in version 1.3.25. [André Malo]

*) mod_deflate: Check also err_headers_out for an already set Content-Encoding: gzip header. This prevents gzip compressed content from a CGI script from being compressed once more. PR 17797. [André Malo]

AVAILABILITY: Complete product bundles are available now on <http://www.software.hp.com/>

**REVISED 01** CHANGE SUMMARY: Rev. 01 Added IPv6 information
----------------------------------------------------------------- A. Background
The Common Vulnerabilities and Exposures project <http://cve.mitre.org/> has identified potential vulnerabilities
in the Apache HTTP Server (CAN-2003-0189, CAN-2003-0245). These affect the following HP products on HP-UX releases B.11.00, B.11.11 and B.11.22:

- HPApache/B9416AA and HPApache/B9416BA (all versions)
- hp-ux apache-based web server products hpuxwsAPACHE and hpuxwsApache, v.1.0.05.01 or earlier.

Note: The following are not vulnerable: HP OpenVMS HP NonStop Servers HP Tru64 UNIX HP Tru64 OpenVMS

**REVISED 01** B. Recommended solution
The Apache Software Foundation has released Apache 2.0.46 as the best known version fixing the potential vulnerabilities mentioned above.

HP has incorporated Apache 2.0.46 in the following product:
- hp-ux apache-based web server v.1.0.06.01 or later, available from: http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
displayProductInfo.pl?productNumber=HPUXWSSUITE
**REVISED 01**
--->> NOTE: The IPv6 solution is now available. Please refer to --->> documentation and depot's available from software.hp.com --->> Click on "internet ready and networking" --->> and look for "hp-ux apache-based web server --->> v.1.0.07.01 for ipv6 powered by apache, tomcat, webmin.

Check for Apache Installation ----------------------------- To determine if the Apache web server from HP is installed on your system, use Software Distributor's swlist command. More than one version may be present on a single system.

For example, the results of the command swlist -l product | grep -i apache

HPApache 2.0.39.01.02 HP Apache-based Web Server hpuxwsAPACHE A.1.0.05.01 HP-UX Apache-based Web Server

Stop Apache ----------------------------- Before updating, make sure to stop any previous Apache binary. Otherwise, the previous binary will continue running, preventing the new one from starting, although the installation would be successful.

After determining which Apache is installed, stop Apache with the following commands:

for HPApache: /opt/hpapache2/bin/apachectl stop for hpuxwsAPACHE: /opt/hpws/apache/bin/apachectl stop

Download and Install Apache ----------------------------- - Download Apache from Software Depot using the previously
mentioned links. - Verify successful download by comparing the cksum with the
value specified on the installation web page. - Use SD to swinstall the depot. - For customers with HPApache/B9416AA or HPApache/B9416BA
installed, migrate to hpuxwsAPACHE/hpuxwsApache and remove the affected products from the system.

Installation of this new version of HP Apache over an existing HP Apache installation is supported, whereas installation over a non-HP Apache is NOT supported.

Removing Apache Installation ---------------------------- If you prefer to remove Apache from your system rather than install a newer version to resolve the security problem, use both Software Distributor's "swremove" command and also "rm -rf" the home location as specified in the rc.config.d file "HOME" variables.

To find the files containing HOME variables in the /etc/rc.config.d directory:

%ls /etc/rc.config.d | grep apache hpapache2conf hpws_apacheconf

Mandrake Linux Security Update Advisory ________________________________________________________________________
Package name: apache2 Advisory ID: MDKSA-2003:063-1 Date: June 2nd, 2003 Original Advisory Date: May 30th, 2003 Affected versions:9.1 ________________________________________________________________________
Problem Description:
Two vulnerabilities were discovered in the Apache web server that affect all 2.x versions prior to 2.0.46. The first, discovered by John Hughes, is a build system problem that allows remote attackers to prevent access to authenticated content when a threaded server is used. This only affects versions of Apache compiled with threaded server "httpd.worker", which is not the default for Mandrake Linux.

The second vulnerability, discovered by iDefense, allows remote attackers to cause a DoS (Denial of Service) condition and may also allow the execution of arbitrary code.

The provided packages include back-ported fixes to correct these vulnerabilities and MandrakeSoft encourages all users to upgrade immediately.

Update:
The previous update mistakenly listed apache-conf packages which were never included, nor intended to be included, as part of the update.

--------------------------------------------------------------------- Red Hat Security Advisory

Synopsis: Updated httpd packages fix Apache security vulnerabilities Advisory ID: RHSA-2003:186-01 Issue date: 2003-05-28 Updated on: 2003-05-28 Product: Red Hat Linux Keywords: Apache httpd auth remote Cross references: Obsoletes: CVE Names: CAN-2003-0189 CAN-2003-0245 ---------------------------------------------------------------------
1. Topic:
Updated httpd packages that fix two security issues are now available for Red Hat Linux 8.0 and 9.
2. Relevant releases/architectures:
Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386
3. Problem description:
The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server.
A bug in Apache 2.0 through 2.0.45 allows remote attackers to cause a denial of service, and may allow execution of arbitrary code. This bug affects both Red Hat Linux 8.0 and 9. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0245 to this issue.
A build system problem in Apache 2.0 through 2.0.45 allows remote attackers to cause a denial of access to authenticated content when a threaded server is used. This bug affects only Red Hat Linux 9 when the threaded server "httpd.worker" has been configured, which is not the default. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0189 to this issue.
All users of the Apache HTTP Web Server are advised to upgrade to the applicable errata packages, which contain back-ported fixes correcting these issues, and applied to Apache version 2.0.40.
After the errata packages are installed, restart the Web service by running the following command:
/sbin/service httpd restart
Red Hat would like to thank iDefense who initially discovered CAN-2003-0245 and John Hughes for CAN-2003-0189.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
88575 - Byte Range implementation fix 89170 - fullstatus segfaults apachectl 89179 - mod_proxy (forward proxy) inserts empty line before header
