Synopsis :

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

Description :

ocert reports :

The dcraw tool, as well as several other projects re-using its code,
suffers from an integer overflow condition which lead to a buffer
overflow.

The vulnerability concerns the 'len' variable, parsed without
validation from opened images, used in the ljpeg_start() function.

A maliciously crafted raw image file can be used to trigger the
vulnerability, causing a Denial of Service condition.
