CVE-2012-0850: Buffer Overflow
First published: Mon Aug 20 2012(Updated: )
The sbr_qmf_synthesis function in libavcodec/aacsbr.c in FFmpeg before 0.9.1 allows remote attackers to cause a denial of service (application crash) via a crafted mpg file that triggers memory corruption involving the v_off variable, probably a buffer underflow.
