Secunia Advisory SA29780

Where:

From remote

Impact:

System access

Solution Status:

Unpatched

CVE Reference(s):

Description


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 6.7.0.22). Other versions may also be affected.


Solution:
Disable the automatic loading of subtitles. Do not open untrusted subtitles.
