1. Summary:

Updated Perl packages that fix security a security issue are now available
for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

Perl is a high-level programming language commonly used for system
administration utilities and Web programming.

Kevin Finisterre discovered a flaw in sperl, the Perl setuid wrapper, which
can cause debugging information to be logged to arbitrary files. By setting
an environment variable, a local user could cause sperl to create, as root,
files with arbitrary filenames, or append the debugging information to
existing files. (CVE-2005-0155)

A fix for this issue was first included in the update RHSA-2005:103
released in February 2005.  However the patch to correct this issue was
dropped from the update RHSA-2005:674 made in October 2005.  This
regression has been assigned CVE-2006-3813.

Users of Perl are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
