CVE-2011-4957  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:12 wordpress to version 3.2.1+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

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.
