The vulnerability (infinite loop triggered by WebSocket frames with invalid 64-bit payload length where MSB is set) was fixed in upstream Apache Tomcat commit f9f75c1467 by Mark Thomas, which shipped in the 7.0.109 release before TuxCare onboarded it. The fix adds validation at WsFrameBase.java:262-265 that rejects negative payload lengths (MSB set), preventing the infinite loop.
