[SECURITY] [DLA 1809-1] libav security update

Package : libav
Version : 6:11.12-1~deb8u7
CVE ID : CVE-2018-15822 CVE-2019-11338

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.
