In FFmpeg 4.0.1, due to a missing check of a profile value before setting it, the ff_mpeg4_decode_picture_header function in libavcodec/mpeg4videodec.c may trigger a NULL pointer dereference while converting a crafted AVI file to MPEG4, leading to a denial of service.

This update for ffmpeg fixes the following issues :

Security issues fixed: CVE-2019-17542: Fixed a heap-buffer overflow in vqa_decode_chunk due to an out-of-array access (bsc#1154064).

CVE-2019-12730: Fixed an uninitialized use of variables due to an improper check (bsc#1137526).

CVE-2018-13301: Fixed a denial of service while converting a crafted AVI file to MPEG4 (bsc#1100352).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
