Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : cups, cupsys vulnerabilities (USN-906-1)

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that the CUPS scheduler did not properly handle
certain network operations. A remote attacker could exploit this flaw
and cause the CUPS server to crash, resulting in a denial of service.
This issue only affected Ubuntu 8.04 LTS, 8.10, 9.04 and 9.10.
(CVE-2009-3553, CVE-2010-0302)

Ronald Volgers discovered that the CUPS lppasswd tool could be made to
load localized message strings from arbitrary files by setting an
environment variable. A local attacker could exploit this with a
format-string vulnerability leading to a root privilege escalation.
The default compiler options for Ubuntu 8.10, 9.04 and 9.10 should
reduce this vulnerability to a denial of service. (CVE-2010-0393).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.9
