==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

USN-1681-1 introduced a regression in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

USN-1681-1 fixed vulnerabilities in Firefox. Due to an upstream regression,
some translations became unusable after upgrading. This update fixes the
problem.

We apologize for the inconvenience.

Original advisory details:

 Christoph Diehl, Christian Holler, Mats Palmgren, Chiaki Ishikawa, Bill
 Gianopoulos, Benoit Jacob, Gary Kwong, Robert O'Callahan, Jesse Ruderman,
 and Julian Seward discovered multiple memory safety issues affecting
 Firefox. If the user were tricked into opening a specially crafted page, an
 attacker could possibly exploit these to cause a denial of service via
 application crash, or potentially execute code with the privileges of the
 user invoking Firefox. (CVE-2013-0769, CVE-2013-0749, CVE-2013-0770)

 Abhishek Arya discovered several user-after-free and buffer overflows in
 Firefox. An attacker could exploit these to cause a denial of service via
 application crash, or potentially execute code with the privileges of the
 user invoking Firefox. (CVE-2013-0760, CVE-2013-0761, CVE-2013-0762,
 CVE-2013-0763, CVE-2013-0766, CVE-2013-0767, CVE-2013-0771, CVE-2012-5829)

 A stack buffer was discovered in Firefox. If the user were tricked into
 opening a specially crafted page, an attacker could possibly exploit this
 to cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking Firefox. (CVE-2013-0768)

 Masato Kinugawa discovered that Firefox did not always properly display URL
 values in the address bar. A remote attacker could exploit this to conduct
 URL spoofing and phishing attacks. (CVE-2013-0759)

 Atte Kettunen discovered that Firefox did not properly handle HTML tables
 with a large number of columns and column groups. If the user were tricked
 into opening a specially crafted page, an attacker could exploit this to
 cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking Firefox. (CVE-2013-0744)

 Jerry Baker discovered that Firefox did not always properly handle
 threading when performing downloads over SSL connections. An attacker could
 exploit this to cause a denial of service via application crash.
 (CVE-2013-0764)

 Olli Pettay and Boris Zbarsky discovered flaws in the Javacript engine of
 Firefox. An attacker could cause a denial of service via application crash,
 or potentially execute code with the privileges of the user invoking
 Firefox. (CVE-2013-0745, CVE-2013-0746)

 Jesse Ruderman discovered a flaw in the way Firefox handled plugins.  If a
 user were tricked into opening a specially crafted page, a remote attacker
 could exploit this to bypass security protections to conduct clickjacking
 attacks. (CVE-2013-0747)

 Jesse Ruderman discovered an information leak in Firefox. An attacker could
 exploit this to reveal memory address layout which could help in bypassing
 ASLR protections. (CVE-2013-0748)

 An integer overflow was discovered in the Javascript engine, leading to a
 heap-based buffer overflow. If the user were tricked into opening a
 specially crafted page, an attacker could possibly exploit this to execute
 code with the privileges of the user invoking Firefox. (CVE-2013-0750)

 Sviatoslav Chagaev discovered that Firefox did not properly handle XBL
 files with multiple XML bindings with SVG content. An attacker could cause
 a denial of service via application crash, or potentially execute code with
 the privileges of the user invoking Firefox. (CVE-2013-0752)

 Mariusz Mlynski discovered two flaws to gain access to privileged chrome
 functions. An attacker could possibly exploit this to execute code with the
 privileges of the user invoking Firefox. (CVE-2013-0757, CVE-2013-0758)

 Several use-after-free issues were discovered in Firefox. If the user were
 tricked into opening a specially crafted page, an attacker could possibly
 exploit this to execute code with the privileges of the user invoking
 Firefox. (CVE-2013-0753, CVE-2013-0754, CVE-2013-0755, CVE-2013-0756)

 Two intermediate CA certificates were mis-issued by the TURKTRUST
 certificate authority. If a remote attacker were able to perform a
 man-in-the-middle attack, this flaw could be exploited to view sensitive
 information. (CVE-2013-0743)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:
