FreeBSD : png -- libpng decompression denial of service (4fb5d2cd-4c77-11df-83fb-0015587e2cc1)

High Nessus Plugin ID 45584


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


A vulnerability in libpng can result in denial of service conditions when a remote attacker tricks a victim to open a specially crafted PNG file.

The PNG project describes the problem in an advisory :

Because of the efficient compression method used in Portable Network Graphics (PNG) files, a small PNG file can expand tremendously, acting as a 'decompression bomb'.

Malformed PNG chunks can consume a large amount of CPU and wall-clock time and large amounts of memory, up to all memory available on a system


Update the affected package.
