## Description

The g2m\_init\_buffers function in libavcodec/g2meet.c in FFmpeg before 2.1
uses an incorrect ordering of arithmetic operations, which allows remote
attackers to cause a denial of service (out-of-bounds array access) or
possibly have unspecified other impact via crafted Go2Webinar data.
