Updated pcre packages that correct two security flaws are now available for Red Hat Enterprise Linux 5. 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. This update has been rated as having critical security impact by the Red Hat Security Response Team.

3. Problem 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.
