RHSA-2008:0532 - Security Advisory

Topic

Updated perl packages that fix a security issue are now available for Red
Hat Application Stack v1.

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

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. A specially crafted
regular expression with Unicode characters could trigger a buffer overflow,
causing Perl to crash, or possibly execute arbitrary code with the
privileges of the user running Perl. (CVE-2008-1927)

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

Solution

Before applying this update, make sure that all previously-released
