Gentoo Linux Security Advisory

Title: CUPS: Integer overflow vulnerability (GLSA 200804-23)
Severity: high
Exploitable: remote, local
Date: April 18, 2008
Bug(s): #217232
ID: 200804-23

Synopsis

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

Background

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

Affected Packages

Package: net-print/cups
Vulnerable: < 1.2.12-r8
Unaffected: >= 1.2.12-r8
Architectures: All supported architectures


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.

Workaround

There is no known workaround at this time.

Resolution

All CUPS users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/cups-1.2.12-r8"


References

CVE-2008-1722
