Description Huzaifa S. Sidhpurwala 2015-05-11 21:11:25 EDT

Security researcher Aki Helin used the Address Sanitizer tool to find a buffer overflow during video playback on Linux systems. This was due to a problem in older versions of the Gstreamer plugin during the parsing of H.264 formatted video. This issue could be used to induce a possibly exploitable crash.

This issue does not affect the current 1.0 version of Gstreamer and does not affect Windows or OS X systems.

Comment 3 Huzaifa S. Sidhpurwala 2015-05-15 04:43:45 EDT

Firefox addresses this issue by blacklisting the affected H.264 video plugin. So even if target system has a vulnerable version of Gstreamer plugin, this issue cannot be exploited remotely by using malicious web content via firefox.

The corresponding gstreamer bug for this issue is:
