Описание
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. This overflow can lead to a heap buffer overflow, enabling out-of-bounds memory writes. The consequence of this vulnerability is potential memory corruption or arbitrary code execution.
Отчет
This is vulnerability in FFmpeg's DVB subtitle parser. While exploitation requires a local attacker to entice a user into processing a specially crafted WTV file, successful exploitation could lead to arbitrary code execution. This risk is elevated due to FFmpeg's common use in multimedia processing within Red Hat environments.
Меры по смягчению последствий
To mitigate this issue, avoid processing untrusted WTV (Windows Recorded TV Show) files, especially those containing DVB subtitles. Exercise caution when handling multimedia files from unknown or suspicious sources.
