First published: Wed Dec 16 2015(Updated: )

Integer underflow in the Metadata::setData function in MetaData.cpp in libstagefright in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code or cause a denial of service (incorrect memory allocation and application crash) via an MP4 video file with crafted covr metadata that triggers a buffer overflow.
