Status

Affected

Vendor Statement

The AIX operating system is vulnerable to the named and DNS resolver issues in releases 4.3.3, 5.1.0 and 5.2.0. Temporary patches will be available through an efix package by 11/22/2002 or before. The efix will be available at the following URL:

ftp://ftp.software.ibm.com/aix/efixes/security/dns_named_efix.tar.Z

In the interim, customers may want to implement the workarounds given in the Solutions section to limit their exposure.

The following APARs will be available in the near future:

AIX 4.3.3 APAR IY37088 (available approx 11/27/2002)
AIX 5.1.0 APAR IY37019 (available approx 12/18/2002)

Affected

Vendor Statement

Older releases (6.2, 7.0) of Red Hat Linux shipped with versions of BIND which may be vulnerable to these issues however a Red Hat security advisory in July 2002 upgraded all our supported distributions to BIND 9.2.1 which is not vulnerable to these issues.

All users who have BIND installed should ensure that they are running these updated versions of BIND.

openpkg-security@openpkg.org                         openpkg@openpkg.org
OpenPKG-SA-2002.011                                          15-Nov-2002
________________________________________________________________________

Package:             bind, bind8
Vulnerability:       denial of service, arbitrary code execution
OpenPKG Specific:    no

Dependent Packages:  none

Affected Releases:   Affected Packages:     Corrected Packages:
OpenPKG 1.0          <= bind-8.2.6-1.0.1    >= bind-8.2.6-1.0.2
OpenPKG 1.1          <= bind8-8.3.3-1.1.0   >= bind8-8.3.3-1.1.1
OpenPKG CURRENT      <= bind8-8.3.3-2002082 >= bind8-8.3.3-20021114

Description:
 The Internet Software Consortium (ISC) [1] has discovered or has been
 notified of several bugs which can result in vulnerabilities of varying
 levels of severity in BIND [2][3]. These problems include buffer overflows,
 stack revealing, divide by zero, null pointer dereferencing, and more [4].
 A subset of these vulnerabilities exist in the BIND packages distributed by
 OpenPKG.

  Please check whether you are affected by running "<prefix>/bin/rpm -qa |
 grep bind". If you have an affected version of the "bind" or "bind8" package
 (see above), upgrade it according to the solution below.

Workaround:
 Because disabling recursion or disabling DNSSEC is a workaround to only a
 subset of the aforementioned problems, it is not a recommended aproach.

Solution:
 Since these vulnerabilities do not exist in BIND version 9.2.1, one solution
 simply involves upgrading to it. The packages bind-9.2.1-1.1.0 in OpenPKG
 1.1 [5], and bind-9.2.1-20021111 in OpenPKG CURRENT [6] are both candidates
 in this respect. Be warned that although such later versions of BIND are
 stable, there exist large differences between BIND 8 and BIND 9 software.

  A lighter approach involves updating existing packages to newly patched
 versions of BIND 8. Select the updated source RPM appropriate
 for your OpenPKG release [7][8][9], and fetch it from the OpenPKG FTP service
 or a mirror location. Verify its integrity [10], build a corresponding
 binary RPM from it and update your OpenPKG installation by applying the
 binary RPM [11]. For the latest OpenPKG 1.1 release, perform the following
 operations to permanently fix the security problem (for other releases
 adjust accordingly).

  $ ftp ftp.openpkg.org
 ftp> bin
 ftp> cd release/1.1/UPD
 ftp> get bind8-8.3.3-1.1.1.src.rpm
 ftp> bye
 $ <prefix>/bin/rpm -v --checksig bind8-8.3.3-1.1.1.src.rpm
 $ <prefix>/bin/rpm --rebuild bind8-8.3.3-1.1.1.src.rpm
 $ su -
 # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/bind8-8.3.3-1.1.1.*.rpm
 # <prefix>/etc/rc bind8 stop start

Trustix Secure Linux Security Advisory #2002-0076

Package name:      bind
Summary:           Remote exploit
Date:              2002-11-15
Affected versions: TSL 1.1, 1.2, 1.5

Package description:
 BIND (Berkeley Internet Name Domain) is an implementation of the DNS
 (Domain Name System) protocols. BIND includes a DNS server (named),
 which resolves host names to IP addresses, and a resolver library
 (routines for applications to use when interfacing with DNS).

Problem description:
 ISS X-Force has found a number of problems in all BIND 8 series up to
 and including 8.2.6 and 8.3.3.  Two of these can cause BIND to crash
 causing a denial of service attack, whereas the last can be used to
 execute arbitary code on the victim.


Action:
 We recommend that all systems with this package installed be upgraded.
 Please note that if you do not need the functionality provided by this
 package, you may want to remove it from your system.
