NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc-selinux package and not the tigervnc-selinux package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

A flaw was found in the X Rendering extension's handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash.
