Ubuntu 11.04 : Firefox vulnerabilities (USN-1222-1)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Benjamin Smedberg, Bob Clary, Jesse Ruderman, Bob Clary, Andrew
McCreight, Andreas Gal, Gary Kwong, Igor Bukanov, Jason Orendorff,
Jesse Ruderman, and Marcia Knous discovered multiple memory
vulnerabilities in the browser rendering engine. An attacker could use
these to possibly execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2011-2995, CVE-2011-2997)

Boris Zbarsky discovered that a frame named 'location' could shadow
the window.location object unless a script in a page grabbed a
reference to the true object before the frame was created. This is in
violation of the Same Origin Policy. A malicious website could
possibly use this to access another website or the local file system.

Ian Graham discovered that when multiple Location headers were
present, Firefox would use the second one resulting in a possible CRLF
injection attack. CRLF injection issues can result in a wide variety
of attacks, such as XSS (Cross-Site Scripting) vulnerabilities,
browser cache poisoning, and cookie theft. (CVE-2011-3000)

Mariusz Mlynski discovered that if the user could be convinced to hold
down the enter key, a malicious website could potential pop up a
download dialog and the default open action would be selected or lead
to the installation of an arbitrary add-on. This would result in
potentially malicious content being run with privileges of the user
invoking Firefox. (CVE-2011-2372, CVE-2011-3001)

Michael Jordon and Ben Hawkes discovered flaws in WebGL. If a user
were tricked into opening a malicious page, an attacker could cause
the browser to crash. (CVE-2011-3002, CVE-2011-3003)

It was discovered that Firefox did not properly free memory when
processing ogg files. If a user were tricked into opening a malicious
page, an attacker could cause the browser to crash. (CVE-2011-3005)

David Rees and Aki Helin discovered a problems in the JavaScript
engine. An attacker could exploit this to crash the browser or
potentially escalate privileges within the browser. (CVE-2011-3232).

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 firefox package.

Risk factor :

Critical / CVSS Base Score : 10.0
