CVE-2017-16803 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
