Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-957-1 fixed vulnerabilities in Firefox and Xulrunner. Daniel
Holbert discovered that the fix for CVE-2010-1214 introduced a
regression which did not properly initialize a plugin pointer. If a
user were tricked into viewing a malicious site, a remote attacker
could use this to crash the browser or run arbitrary code as the user
invoking the program. (CVE-2010-2755)

This update fixes the problem.

If was discovered that Firefox could be made to access freed memory.
If a user were tricked into viewing a malicious site, a remote
attacker could cause a denial of service or possibly execute arbitrary
code with the privileges of the user invoking the program. This issue
only affected Ubuntu 8.04 LTS. (CVE-2010-1121)

Several flaws were discovered in the browser engine of
Firefox. If a user were tricked into viewing a malicious
site, a remote attacker could cause a denial of service or
possibly execute arbitrary code with the privileges of the
user invoking the program. (CVE-2010-1200, CVE-2010-1201,
CVE-2010-1202, CVE-2010-1203)

A flaw was discovered in the way plugin instances
interacted. An attacker could potentially exploit this and
use one plugin to access freed memory from a second plugin
to execute arbitrary code with the privileges of the user
invoking the program. (CVE-2010-1198)

An integer overflow was discovered in Firefox. If a user
were tricked into viewing a malicious site, an attacker
could overflow a buffer and cause a denial of service or
possibly execute arbitrary code with the privileges of the
user invoking the program. (CVE-2010-1196)

Martin Barbella discovered an integer overflow in an XSLT
node sorting routine. An attacker could exploit this to
overflow a buffer and cause a denial of service or possibly
execute arbitrary code with the privileges of the user
invoking the program. (CVE-2010-1199)

Michal Zalewski discovered that the focus behavior of
Firefox could be subverted. If a user were tricked into
viewing a malicious site, a remote attacker could use this
to capture keystrokes. (CVE-2010-1125)

Ilja van Sprundel discovered that the 'Content-Disposition:
attachment' HTTP header was ignored when 'Content-Type:
multipart' was also present. Under certain circumstances,
this could potentially lead to cross-site scripting attacks.
(CVE-2010-1197)

Amit Klein discovered that Firefox did not seed its random
number generator often enough. An attacker could exploit
this to identify and track users across different web sites.
(CVE-2008-5913).
