FreeBSD : lighttpd -- DOS when access files with mtime 0 (5678da43-ea99-11db-a802-000fea2763ce)

high Nessus Plugin ID 25049

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Lighttpd SA :

Lighttpd caches the rendered string for mtime. The cache key has as a default value 0. At that point the pointer to the string are still NULL. If a file with an mtime of 0 is requested it tries to access the pointer and crashes.

The bug requires that a malicious user can either upload files or manipulate the mtime of the files.

The bug was reported by cubiq and fixed by Marcus Rueckert.

Solution

Update the affected package.
