CVE-2023-40052: Progress Openedge

This issue affects Progress Application Server (PAS) for OpenEdge in versions 11.7 prior to 11.7.18, 12.2 prior to 12.2.13, and innovation releases prior to 12.8.0 .  An attacker who can produce a malformed web request may cause the crash of a PASOE agent potentially disrupting the thread activities of many web application clients.
