NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc package and not the tigervnc package as distributed by RHEL.

A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIPassiveUngrab request accesses out-of-bounds memory when invoked with a high keycode or button code. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.
