CVE-2011-4957 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Ubuntu.
The make_clickable function in wp-includes/formatting.php in WordPress before 3.1.1 does not properly check URLs before passing them to the PCRE library, which allows remote attackers to cause a denial of service (crash) via a comment with a crafted URL that triggers many recursive calls.
