Red Hat Product Errata RHSA-2014:1436 0 normal SHIPPED_LIVE Moderate: X11 client libraries security, bug fix, and enhancement update 2014-10-14 01:06:02 UTC

Description Huzaifa S. Sidhpurwala 2013-05-03 07:39:02 UTC 
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()
