Advisory: RHSA-2007:1011-3
Type: Security Advisory
Severity: Important
Issued on: 2007-11-05
Last updated on: 2007-11-05
Affected Products: Red Hat Application Stack v1 for Enterprise Linux AS (v.4)
Red Hat Application Stack v1 for Enterprise Linux ES (v.4)
CVEs (cve.mitre.org): CVE-2007-5116

Details

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.

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.
