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 Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check.
