Summary
Red Hat Security Advisory: perl security update

Notes

Topic
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.
Details
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.
