Description Huzaifa S. Sidhpurwala 2013-05-07 06:17:16 UTC
Multiple integer overflows leading to heap-based buffer overflows were found in several functions in libXtst, an X.Org X11 libXtst runtime library. When a X client is connected to a malicious X server, (modified to return invalid values), it can cause arbirary code execution with the privileges of the user running the X client.

      Affected functions:  XRecordGetContext()
