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

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company will

Security Bulletin as soon as possible.

PROBLEM:  Security vulnerability in ypserv

IMPACT:   Potential for remotely triggered memory leak

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

SOLUTION: Apply the appropriate patch.

AVAILABILITY: The RPMs are available now.

 A. Background

    Ypserv is an NIS authentication server.  Ypserv versions
    before 2.5 contain a memory leak that can potentially be triggered
    remotely.  Ypserv is not included in the default installation of
    HP Secure OS Software for Linux.

 B. Recommended solution

    Hewlett-Packard Company recommends that customers who have
    installed ypserv download the RPMs listed in the
    following Red Hat Security Advisory in the section labeled
    "Red Hat Linux 7.1".

    2002-10-24 RHSA-2002:223  Updated ypserv packages fixes memory leak

    To install the security advisory 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 advisory RPM.

           tripwire --check --interactive

    2. Install the advisory RPM from the root account.

           rpm -F <advisory RPM name>

    3. Update the tripwire database

           tripwire --check --interactive

    The rpm -q <package name> command can be used to determine if
    the package is installed. Hewlett-Packard recommends applying the
    security advisory 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 To find the latest dependent
    RPM enter the RPM's name in the "By Keyword" box.
