   The security bulletins digest has been split into multiple digests
   based on the operating system (HP-UX, MPE/iX, and HP Secure OS
   Software for Linux). You will continue to receive all security
   bulletin digests unless you choose to update your subscriptions.
   
   To update your subscriptions, use your browser to access the
   IT Resource Center on the World Wide Web at:

TEXT

---------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBTL0208-061
    Originally issued: 15 Aug 2002
---------------------------------------------------------------

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 XDR decoder

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

DAMAGE: Potential remote command execution

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. Sun RPC is a remote procedure call
    framework which allows clients to invoke procedures in a server
    process over a network. XDR is a mechanism for encoding data
    structures for use with RPC. NFS, NIS, and many other network
    services are built upon Sun RPC. Glibc contains an XDR encoder/
    decoder derived from Sun's RPC implementation which was recently
    demonstrated to have a potential security vulnerability.

    This problem has been reported in CERT Security Advisory CA-2002-25.

 B. Fixing the problem

    Hewlett-Packard Company recommends that customers install the RPMs
    listed in the following Red Hat Security Advisory in the section
    labeled "Red Hat Linux 7.1 i386".

    2002-08-12 RHSA-2002:166 Updated glibc packages fix
                              vulnerabilities in RPC XDR decoder

    http://rhn.redhat.com/errata/RHSA-2002-166.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.
