NVD Description

Note: Versions mentioned in the description apply only to the upstream jws5-tomcat package and not the jws5-tomcat package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.
