Detailsinfo

A vulnerability classified as critical was found in Mozilla Firefox 27.0 (Web Browser). This vulnerability affects an unknown functionality of the file TypedArrayObject.cpp. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

vmtypedarrayobject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not validate the length of the destination array before a copy operation, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write and application crash) by triggering incorrect use of the TypedArrayObject class.

The weakness was shared 03/18/2014 by George Hotz as MFSA2014-32 as confirmed advisory (Website) via Pwn2Own Contest. The advisory is shared for download at mozilla.org. This vulnerability was named CVE-2014-1514 since 01/16/2014. The attack can be initiated remotely. No form of authentication is required for a successful exploitation.
