The atrac3_decode_init function in libavcodec/atrac3.c in FFmpeg before 1.0.4 allows remote attackers to have an unspecified impact via ATRAC3 data with the joint stereo coding mode set and fewer than two channels. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-0858 (From OE-Core rev: 0ee8754c973f5eff3ba4d00319a5308888c12b17) Signed-off-by: Yue Tao <Yue.Tao@windriver.com> Signed-off-by: Roy Li <rongqing.li@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
