Vulnerability Name:

CVE-2012-1699 (CCN-80789)

Assigned:2012-07-24
Published:2012-07-24
Updated:2017-09-19
Summary:The ProcSetEventMask function in difs/events.c in the xfs font server for X.Org X11R6 through X11R6.6 and XFree86 before 3.3.3 calls the SendErrToClient function with a mask value instead of a pointer, which allows local users to cause a denial of service (memory corruption and crash) or obtain potentially sensitive information from memory via a SetEventMask request that triggers an invalid pointer dereference.
