Some vulnerabilities have been discovered in DivX Player, which can potentially be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors in the processing of subtitle files (*.SRT, *.SUB). These can be exploited to cause stack-based buffer overflows via a specially crafted, overly long subtitle line contained in a malicious SRT or SUB file.
Successful exploitation may allow execution of arbitrary code, but requires that the user is tricked into opening a specially crafted SRT or SUB file.
The vulnerability is confirmed in DivX Player 6.7 (build 220.127.116.11). Other versions may also be affected.
Solution: Disable the automatic loading of subtitles. Do not open untrusted subtitles.
