Descriptions

The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file.

La función update_dimensions en libavcodec/vp8.c en FFmpeg hasta la versión 2.8.1, como se utiliza en Google Chrome en versiones anteriores a 46.0.2490.71 y otros productos, confía en una cuenta de partición de coeficiente durante una operación multi-hilo, lo que permite a atacantes remotos provocar una denegación de servicio (condición de carrera y corrupción de memoria) o posiblemente tener otro impacto no especificado a través de un archivo WebM manipulado.
