USN-1681-1 fixed vulnerabilities in Firefox. Due to an upstream regression, Firefox suffered from instabilities when accessing some websites. This update fixes the problem.

We apologize for the inconvenience.

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).
