Synopsis

A vulnerability in CUPS might allow for the execution of arbitrary code or a Denial of Service.

2. Impact Information

Background

CUPS provides a portable printing layer for UNIX-based operating systems.

Description

Thomas Pollet reported a possible integer overflow vulnerability in the PNG image handling in the file filter/image-png.c.

Impact

A malicious user might be able to execute arbitrary code with the privileges of the user running CUPS (usually lp), or cause a Denial of Service by sending a specially crafted PNG image to the print server. The vulnerability is exploitable via the network if CUPS is sharing printers remotely.
