Description D'juan McDonald (domhnall) 2017-11-14 07:27:55 UTC

CVE-2017-16803(https://nvd.nist.gov/vuln/detail/CVE-2017-16803):
In Libav through 11.11 and 12.x through 12.1, the smacker_decode_tree function in libavcodec/smacker.c does not properly restrict tree recursion, which allows remote attackers to cause a denial of service (bitstream.c:build_table() out-of-bounds read and application crash) via a crafted Smacker stream.

Upstream Fix:
https://github.com/libav/libav/commit/cd4663dc80323ba64989d0c103d51ad3ee0e9c2f

@maintainer(s), noting 12.1 in tree. In case of bump, please call for stabilization, thank you.
