CVE-2015-8365

The smka_decode_frame function in libavcodec/smacker.c does not verify that
the data size is consistent with the number of channels, which allows remote
attackers to cause a denial of service (out-of-bounds array access) or
possibly have unspecified other impact via crafted Smacker data.

CVE-2017-7208

The decode_residual function in libavcodec allows remote attackers to cause
a denial of service (buffer over-read) or obtain sensitive information from
process memory via a crafted h264 video file.

CVE-2017-7862

The decode_frame function in libavcodec/pictordec.c is vulnerable to an
out-of-bounds write caused by a heap-based buffer overflow.

CVE-2017-9992

The decode_dds1 function in libavcodec/dfa.c allows remote attackers to
cause a denial of service (Heap-based buffer overflow and application crash)
or possibly have unspecified other impact via a crafted file.

For Debian 7 "Wheezy", these problems have been fixed in version
6:0.8.21-0+deb7u1.

We recommend that you upgrade your libav packages.
