Description

The (1) SProcRecordCreateContext and (2) SProcRecordRegisterClients functions in the Record extension and the (3) SProcSecurityGenerateAuthorization function in the Security extension in the X server 1.4 in X.Org X11R7.3 allow context-dependent attackers to execute arbitrary code via requests with crafted length values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption.
