CVE-2015-6820

Publication date 5 September 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
