TEXT

---------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBTL0207-053
    Originally issued: 25 JUL '02
---------------------------------------------------------------

The information in the following Security Bulletin should be acted
upon as soon as possible. Hewlett-Packard Company will not be
liable for any consequences to any customer resulting from the
customer's failure to fully implement instructions in this Security
Bulletin as soon as possible.

Because the vulnerability does not require a HP Secure OS
1.0 patch or re-packaging of the RPM affected by the bulletin, the
RPMs have not been produced or tested by Hewlett-Packard Company.

---------------------------------------------------------------
PROBLEM: Security vulnerability in glibc resolver

PLATFORM: Any system running HP Secure OS software for Linux Release 1.0

DAMAGE: Potential remote execution of commands by an intruder

SOLUTION: Apply the appropriate RPMs (see section B below)

MANUAL ACTIONS: None

AVAILABILITY: The RPMs are available now.
---------------------------------------------------------------
 A. Background

    The glibc package contains standard libraries which are used by
    multiple programs on the system.
 
    A vulnerability exists in glibc and glibc-compat that could be used
    by an intruder to execute arbitrary code

 B. Fixing the problem

    Hewlett-Packard Company recommends that customers who have installed
    glibc download the RPMs listed in the following Red Hat
    Security Advisory:

    2002-07-22 RHSA-2002:139 Updated glibc packages fix vulnerabilities
                              in resolver

    http://rhn.redhat.com/errata/RHSA-2002-139.html

    To install the security bulletin RPMs, use the following sequence
    of commands:

    1. If you use the tripwire product, we recommend that you run a
       a consistency check and fix any violations before installing
       the security bulletin RPM.

           tripwire --check --interactive

    2. Install the bulletin RPM from the root account.

           rpm -F <bulletin RPM name>

    3. Update the tripwire database

           tripwire --check --interactive

    NOTE:
    The rpm -q <package name> command can be used to determine if the
    package is installed. Hewlett-Packard Company recommends applying the
    Security Bulletin fixes to installed packages only. The -F option
    to the RPM installer will only apply the fix if the package is
    currently installed on the system. Dependent RPMs can be found by
    using the "Find Latest RPMs" search facility at
    http://www.redhat.com/apps/download. To find the latest dependent
    RPM enter the RPM's name in the "By Keyword" box.
