FFmpeg versions from 0.5 up to, but not including, 9.0 contain a signed integer overflow vulnerability in the DVB subtitle parser in libavcodec/dvbsub_parser.c that allows attackers to trigger a heap buffer overflow by supplying a crafted WTV file. The overflow causes the bounds-check guard expression to wrap to INT_MIN, bypassing the PARSE_BUF_SIZE comparison and invoking memcpy() with attacker-controlled data into a heap buffer, resulting in an out-of-bounds heap write and potential memory corruption or code execution. A flaw was found in FFmpeg. An attacker could exploit a signed integer overflow vulnerability within the DVB subtitle parser by providing a specially crafted WTV (Windows Recorded TV Show) file. While exploitation requires a local attacker to entice a user into…
