RHSA-2007:0967 - Critical: pcre security update
Synopsis
Critical: pcre security update
Type/Severity
Security Advisory Critical
Topic
Updated pcre packages that correct two security flaws are now available for Red Hat Enterprise Linux 5.
This update has been rated as having critical security impact by the Red Hat Security Response Team.
Description
PCRE is a Perl-compatible regular expression library.
Multiple flaws were found in the way pcre handles certain malformed regular expressions. If an application linked against pcre, such as Konqueror, parses a malicious regular expression, it may be possible to run arbitrary code as the user running the application. (CVE-2007-1659, CVE-2007-1660)
Users of pcre are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
Red Hat would like to thank Tavis Ormandy and Will Drewry for properly disclosing these issues.
