NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc-server-module package and not the tigervnc-server-module package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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 device ID is found, which can lead to out-of-bounds memory access.
