ROS-20220112-01

A vulnerability in the X.Org Server - X Window System server implementation is caused by an out-of-memory write in the
SProcScreenSaverSuspend() function in the Screen Saver extension. Exploitation of the vulnerability could allow
an attacker to send a specially crafted suspend request, initiate an unrestricted write, and
execute arbitrary code with elevated privileges

A vulnerability in the X.Org Server - X Window System server implementation is caused by a write beyond memory boundaries in the
ProcXFixesCreatePointerBarrier() function in the XFixes extension. Exploitation of the vulnerability could allow an
an attacker to send a specially crafted CreatePointerBarrier request, initiate a write outside of the
bounds and execute arbitrary code with elevated privileges

A vulnerability in the X.Org Server - X Window System server implementation is caused by an out-of-bounds memory write in the
SwapCreateRegister() function in the Record extension. Exploitation of the vulnerability could allow an attacker to
send specially crafted RecordCreateContext and RecordRegisterClients requests, trigger a record beyond the
out of bounds and execute arbitrary code with elevated privileges

A vulnerability in the X.Org Server - X Window System server implementation is caused by an out-of-bounds memory write in the
SProcRenderCompositeGlyphs() function in the Render extension. Exploitation of the vulnerability could allow
an attacker to send a specially crafted CompositeGlyphs request, initiate an out-of-bounds write
bounds and execute arbitrary code with elevated privileges
