UPDATE: (SSRTM541)Tru64 UNIX CDE, NFS and NIS related Potential
        Security Vulnerabilities

Posted at http://ftp.support.compaq.com/patches/.new/security.shtml

NOTICE: There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.


RELEASE DATE: 17 April, 2002 (SSRT-541)
LAST UPDATED: 22 May, 2002   (SSRTM541) New Patches

SEVERITY:  1

SOURCE:  Compaq Computer Corporation
        Compaq Services
        Software Security Response Team

REFERENCE:  [security bulletin posted 17 April, 2002]
           (SSRT-541) Tru64 UNIX CDE, NFS and NIS related Potential
           Security Vulnerabilities

PROBLEM SUMMARY:
A number of potential security vulnerabilities in Tru64 UNIX V4.0F,
V4.0G, V5.0A, V5.1 and V5.1A, have recently been reported for CDE,
libc, and NFS where, under certain circumstances, system integrity
may be compromised by a malicious user.

 o CDE (severity high)
  o dtaction potential buffer overflow (SSRT0752U)
  o ttsession potential buffer overflow (SSRT0753U)
  o dtprintinfo potential buffer overflow (SSRT0757U, SSRT0788U)
  o dtspcd potential buffer overflow. (SSRT0782U)
    NOTE: cross-reference : (CVE CVE-2001-0803,CERT CA-2001-31,
    CA-2002-01)
    Compaq has not been able to reproduce the problem identified
    in the CERT advisory for any Compaq OS. However with the
    information available, we are including a code change for
    dtspcd that will further reduce any potential buffer overflow
    vulnerability.
      o Buffer overflow attacks are commonly used to attempt to
        subvert the function of a privileged program and
        possibly execute commands at the elevated privileges if
        the program file has the setuid privilege.

 o Environment Variable LANG and LOCPATH (severity high)
  o libc (SSRT0771U)
      A libc environment variable corruption with LANG and
      LOCPATH , may cause a potential buffer overflow

 o NIS Network Information Service (severity moderate)
   o ypbind may core during nmap portscan (SSRT0781U)
      o Core: A file that is a copy of the contents of a
         processes memory, that can be produced when that
         process is aborted by certain kinds of internal error.

 o NFS Network File System (severity moderate)
   o NFS Potential packet flood denial of service (DoS) (SSRT1-26)
      NOTE: Applies to V4.0g PK3 (BL17) & V5.0a PK3 (BL17) only
      A remote user with malicious intent may cause a potential
      denial of service (DoS) with portmap server.

       o Network DoS attacks make computer systems inaccessible
        by flooding a service, server or network with useless
        traffic.

VERSIONS IMPACTED:

 TRU64 UNIX Versions Impacted

 V5.1A PK1 (BL1)
V5.1  PK4 (BL18)
V5.0A PK3 (BL17)
V4.0F PK7 (BL18)
V4.0G PK3 (BL17)


RESOLUTION:

The potential vulnerabilities noted below have been corrected and
newly released patches are now available for TRU64 UNIX.

Compaq strongly recommends that systems be updated to at least the
prerequisite version of TRU64 UNIX and PK release, then install the
previously released security patches identified in the security
bulletin
http://ftp.support.compaq.com/patches/.new/html/SSRT0742U-59U.shtml
prior to installing the following ERP (Early Release Patch).

 UPDATE: 5/22/2002  Updated ERPs are now available for all supported
versions of Tru64 UNIX and will be available in the next aggregate
patch kits for each supported product version.  Until these Tru64
UNIX fixes are available in mainstream patch kits, Compaq recommends
use of the following ERP kits:

  NOTE:  Please review the README file(s) for each patch prior to
        installation.

  The Early Release Patch kits use dupatch to install and will not
 install over any installed Customer-Specific-Patches (CSPs) which
 have file intersections with the ERPs.  Contact your normal support
 channel for assistance if the installation of the ERPs are blocked
 by any of your installed CSPs.

subsequent restore operations begin with updated software. Otherwise,
you must reapply the update after any future restore operation. Any
future upgrades or patch release installations to your system will
require the re-application of the appropriate ERP (identified above).

________________________________________________________________________________

1.  Bulletins Topics

    Sun announces the release of patches for Solaris(tm) 8, 7, 2.6,
    and 2.5.1 (SunOS(tm) 5.8, 5.7, 5.6, and 5.5.1) which relate to a
    buffer overflow in dtspcd.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running the CDE Subprocess control service,
    dtspcd, on SunOS 5.8, 5.7, 5.6, and 5.5.1.

2.  Who is Affected

    Vulnerable:SunOS 5.8, 5.8_x86, 5.7, 5.7_x86, 5.6,
               5.6_x86, 5.5.1, and 5.5.1_x86

3.  Understanding the Vulnerability

    The CDE Subprocess Control Service (dtspcd) daemon accepts requests
    from CDE clients to execute commands and launch applications on the
    local system running the dtspcd daemon.  The dtspcd daemon is spawned
    by the inetd daemon (see inetd(1M)) in response to a CDE client
    request. dtspcd is normally configured to run on port 6112/tcp with
    root privileges.

    A buffer overflow has been discovered in dtspcd which may be
    exploited by a local or a remote attacker to gain root access on the
    affected system.  Any system that does not run the CDE Subprocess
    Control service, dtspcd, is not vulnerable to this problem.  This
    issue was discovered by ISS X-Force who published an advisory at:

    http://xforce.iss.net/alerts/advise101.php

    CERT Advisory CA-2001-31 is available from:

    http://www.cert.org/advisories/CA-2001-31.html

4.  List of Patches

    The following patches are available in relation to the above issue.

    OS Version               Patch ID
    __________               _________
    SunOS 5.8                108949-07
