"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.

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."
