Detail

Problem Description:

Updated Perl packages that fix security issues for Red Hat Application Stack v1.2 are now available.

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

2. Relevant releases/architectures:

Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64 Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64

3. Problem description:

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

A flaw was found in Perl's regular expression engine. Specially crafted input to a regular expression can cause Perl to improperly allocate memory, possibly resulting in arbitrary code running with the permissions of the user running Perl. (CVE-2007-5116)

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

Red Hat would like to thank Tavis Ormandy and Will Drewry for properly disclosing this issue.

4. Solution:

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

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

323571 - CVE-2007-5116 perl regular expression UTF parsing errors
