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 AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A flaw was found in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when computing request length, which allows a client to bypass length checks.
