Detailsinfo

A vulnerability, which was classified as critical, was found in Mozilla Firefox up to 40 on Linux (Web Browser). This affects an unknown code of the file gfx/2d/DataSurfaceHelpers.cpp of the component Cairo Graphics Library. The manipulation with an unknown input leads to a memory corruption vulnerability.
