Description Huzaifa S. Sidhpurwala 2013-05-07 02:06:22 EDT
Multiple integer overflows leading to heap-based buffer overflows were found in several functions in libXp, an X.Org X11 libXp 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.
