NVD Description

Heap-based buffer overflow in the nsBMPEncoder::AddImageFrame function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code via a crafted image data that is mishandled during the encoding of an image frame to an image.
