CVE-2013-2005 libXt: Memory corruption due to unchecked use of unchecked function pointers
Last modified: 2014-10-17 03:42:43 EDT
It was found that multiple functions in libXt, an X.Org X11 libXt runtime library, did not check for the failure of XGetWindowProperty() function to initiase certain valid window properties. This could lead to use of uninitialized pointers for reading, writing or even passing to functions such as free(), this could lead to arbitrary code execution with the privileges of the user running the X client.
Affected functions: ReqCleanup(), HandleSelectionEvents(),
ReqTimedOut(), HandleNormal(), HandleSelectionReplies()
