Detailsinfo

A vulnerability was found in Mozilla Firefox up to 34.0.5 (Web Browser). It has been rated as critical. This issue affects an unknown code. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability.

The weakness was disclosed 01/13/2015 by Christian Holler and Patrick McManus as MFSA2015-01 as confirmed advisory (Website). The advisory is shared at mozilla.org. The public release has been coordinated in cooperation with Mozilla. The identification of this vulnerability is CVE-2014-8634 since 11/06/2014. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. The advisory points out:

Mozilla developers and community identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

The vulnerability scanner Nessus provides a plugin with the ID 81041 (Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : firefox regression (USN-2458-3)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 167588 (OpenSuSE Security Update for seamonkey (openSUSE-SU-2015:0192-1)). The advisory illustrates:

In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.

Upgrading to version 35 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (99955), Tenable (81041), SecurityFocus (BID 72049†), Secunia (SA62237†) and SecurityTracker (ID 1031533†). bugzilla.mozilla.org is providing further details. The entries VDB-68598, VDB-68599, VDB-68600 and VDB-68601 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
