GLSA-200804-01 : CUPS: Multiple vulnerabilities

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200804-01
(CUPS: Multiple vulnerabilities)

Multiple vulnerabilities have been reported in CUPS:
regenrecht (VeriSign iDefense) discovered that the
cgiCompileSearch() function used in several CGI scripts in CUPS'
administration interface does not correctly calculate boundaries when
processing a user-provided regular expression, leading to a heap-based
buffer overflow (CVE-2008-0047).
Helge Blischke reported a
double free() vulnerability in the process_browse_data() function when
adding or removing remote shared printers (CVE-2008-0882).
Tomas Hoger (Red Hat) reported that the gif_read_lzw() function
uses the code_size value from GIF images without properly checking it,
leading to a buffer overflow (CVE-2008-1373).
An unspecified
input validation error was discovered in the HP-GL/2 filter
(CVE-2008-0053).

Impact :

A local attacker could send specially crafted network packets or print
jobs and possibly execute arbitrary code with the privileges of the
user running CUPS (usually lp), or cause a Denial of Service. The
vulnerabilities are exploitable via the network when CUPS is sharing
printers remotely.

Workaround :

There is no known workaround at this time.

Solution :

All CUPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-print/cups-1.2.12-r7'

Risk factor :

Critical / CVSS Base Score : 10.0
