Multiple input validation failures in X server extensions ========================================================= All of the following issues can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. * CVE-2021-4008/ZDI-CAN-14192 SProcRenderCompositeGlyphs out-of-bounds access The handler for the CompositeGlyphs request of the Render extension does not properly validate the request length leading to out of bounds memory write. * CVE-2021-4009/ZDI-CAN 14950 SProcXFixesCreatePointerBarrier out-of-bounds access The handler for the CreatePointerBarrier request of the XFixes extension does not properly validate the request length leading to out of bounds memory write. * CVE-2021-4010/ZDI-CAN-14951 SProcScreenSaverSuspend out-of-bounds access The handler for the Suspend request of the Screen Saver extension does not properly validate the request length leading to out of bounds memory write. * CVE-2021-4011/ZDI-CAN-14952 SwapCreateRegister out-of-bounds access The handlers for the RecordCreateContext and RecordRegisterClients requests of the Record extension do not properly validate the request length leading to out of bounds memory write. --- Need to bump to both xorg-server 21.1.2 and xwayland 21.1.4. Hopefully these patches were backported to the older branch too.
xorg-server-1.20.14 is released with these fixes.
