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 :

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).

Solution :

Update the affected packages.
