"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."

These security issues were fixed :

  - CVE-2018-15822: The flv_write_packet function did not

    failure and DoS (bsc#1105869).

  - CVE-2018-13300: An improper argument passed to the

    out-of-array read while converting a crafted AVI file to
    MPEG4, leading to a denial of service and possibly an
    information disclosure (bsc#1100348).

These non-security issues were fixed :

  - Enable webvtt encoders and decoders (boo#1092241).

  - Build codec2 encoder and decoder, add libcodec2 to
    enable_decoders and enable_encoders.

  - Enable mpeg 1 and 2 encoders."
