"Two more security issues have been corrected in multiple demuxers and
decoders of the libav multimedia library.

CVE-2018-15822

The flv_write_packet function in libavformat/flvenc.c in libav did not
check for an empty audio packet, leading to an assertion failure.

CVE-2019-11338

libavcodec/hevcdec.c in libav mishandled detection of duplicate first
slices, which allowed remote attackers to cause a denial of service
(NULL pointer dereference and out-of-array access) or possibly have
unspecified other impact via crafted HEVC data.

For Debian 8 'Jessie', these problems have been fixed in version
6:11.12-1~deb8u7.

We recommend that you upgrade your libav packages.

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