xorg: xwayland: Use of uninitialized pointer in compRedirectWindow()

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow will return a BadAlloc error without validating the window tree marked just before, which leaves the...

xorg: xwayland: Buffer overflow in XkbChangeTypesOfKey()

A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because t...

xorg: xwayland: Use-after-free in SyncInitTrigger()

A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger is called. If one of the changes triggers an error, the function will return...

Xorg: xwayland: Buffer overflow in XkbVModMaskText()

A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size...

xorg: xwayland: Out-of-bounds write in CreatePointerBarrierClient()

An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching...

X.Org Server compRedirectWindow Type Confusion Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of window...
