Detailsinfo

A vulnerability was found in Mozilla Firefox up to 28.0.1 (Web Browser). It has been declared as critical. Affected by this vulnerability is an unknown part of the component XBL Object Handler. 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.

The nsXBLProtoImpl::InstallImplementation function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 does not properly check whether objects are XBL objects, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via crafted JavaScript code that accesses a non-XBL object as if it were an XBL object.
