Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : cups, cupsys vulnerabilities (USN-952-1)

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 :

Adrian Pastor and Tim Starling discovered that the CUPS web interface
incorrectly protected against cross-site request forgery (CSRF)
attacks. If an authenticated user were tricked into visiting a
malicious website while logged into CUPS, a remote attacker could
modify the CUPS configuration and possibly steal confidential data.
(CVE-2010-0540)

It was discovered that CUPS did not properly handle memory allocations
in the texttops filter. If a user or automated system were tricked
into printing a crafted text file, a remote attacker could cause a
denial of service or possibly execute arbitrary code with privileges
of the CUPS user (lp). (CVE-2010-0542)

Luca Carettoni discovered that the CUPS web interface incorrectly
handled form variables. A remote attacker who had access to the CUPS
web interface could use this flaw to read a limited amount of memory
from the cupsd process and possibly obtain confidential data.
(CVE-2010-1748).

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.
