Descriptions
In FFmpeg before 4.2, avcodec_open2 in libavcodec/utils.c allows a NULL pointer dereference and possibly unspecified other impact when there is no valid close function pointer.
En FFmpeg versiones anteriores a 4.2, la función avcodec_open2 en el archivo libavcodec/utils.c permite una desreferencia del puntero NULL y posiblemente otro impacto no especificado cuando no existe un puntero de función de cierre válido.
It was discovered that FFmpeg incorrectly verified empty audio packets or HEVC data. An attacker could possibly use this issue to cause a denial of service via a crafted file. This issue only affected Ubuntu 16.04 LTS, as it was already fixed in Ubuntu 18.04 LTS.
