A vulnerability classified as very critical was found in Mozilla Firefox 43 (Web Browser). This vulnerability affects the function BufferSubData of the component WebGL. 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:

Buffer overflow in the BufferSubData function in Mozilla Firefox before 44.0 and Firefox ESR 38.x before 38.6 allows remote attackers to execute arbitrary code via crafted WebGL content.

The weakness was released 01/26/2016 by Aki Helin with Oulu University Secure Programming Group as MFSA2016-03 as confirmed security advisory (Website). The advisory is available at mozilla.org. This vulnerability was named CVE-2016-1935 since 01/19/2016. The attack can be initiated remotely. No form of authentication is required for a successful exploitation.
