Ubuntu 6.10 / 7.04 / 7.10 : firefox regression (USN-546-2)

Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-546-1 fixed vulnerabilities in Firefox. The upstream update
included a faulty patch which caused the drawImage method of the
canvas element to fail. This update fixes the problem.

We apologize for the inconvenience.

It was discovered that Firefox incorrectly associated redirected sites
as the origin of 'jar:' contents. A malicious web site could exploit
this to modify or steal confidential data (such as passwords) from
other web sites. (CVE-2007-5947)

Various flaws were discovered in the layout and JavaScript
engines. By tricking a user into opening a malicious web
page, an attacker could execute arbitrary code with the
user's privileges. (CVE-2007-5959)

Gregory Fleischer discovered that it was possible to use
JavaScript to manipulate Firefox's Referer header. A
malicious web site could exploit this to conduct cross-site
request forgeries against sites that relied only on Referer
headers for protection from such attacks. (CVE-2007-5960).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 9.3
