A vulnerability was found in Mozilla Firefox up to 46 (Web Browser). It has been classified as critical. This affects some unknown processing of the component SVG Element Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 allows remote attackers to execute arbitrary code via foreign-context HTML5 fragments, as demonstrated by fragments within an SVG element.
