Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Secunia reports :

ShAnKaR has discovered a vulnerability in phpBB, which can be
exploited by malicious users to compromise a vulnerable system.

Input passed to the 'avatar_path' parameter in admin/admin_board.php
is not properly sanitised before being used as a configuration
variable to store avatar images. This can be exploited to upload and
execute arbitrary PHP code by changing 'avatar_path' to a file with a
trailing NULL byte.

Successful exploitation requires privileges to the administration
section.
