TITLE:
WordPress Trackback Denial of Service Vulnerability

SECUNIA ADVISORY ID:
SA37088

VERIFY ADVISORY:
http://secunia.com/advisories/37088/

DESCRIPTION:
A vulnerability has been reported in WordPress, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to the wp-trackback.php script
letting users pass multiple source character encodings to the
"mb_convert_encoding()" function, which can be used to cause a high
CPU load, potentially resulting in a DoS.

The vulnerability is reported in versions prior to 2.8.5.

SOLUTION:
Update to version 2.8.5.
