CVE-2015-6820 (retired)

Priority
Description
The ff_sbr_apply function in libavcodec/aacsbr.c in FFmpeg before 2.7.2
does not check for a matching AAC frame syntax element before proceeding
with Spectral Band Replication calculations, which allows remote attackers
to cause a denial of service (out-of-bounds array access) or possibly have
unspecified other impact via crafted AAC data.
