NVD Description

Note: Versions mentioned in the description apply only to the upstream openjdk-17-openj9 package and not the openjdk-17-openj9 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

In Eclipse OpenJ9 versions prior to 0.63.0, the JITServer component is vulnerable to a pre-authentication remote denial of service. When processing the initial 4-byte length field of an incoming TCP connection, an integer overflow in MessageBuffer::computeRequiredCapacity() causes the receiving compilation worker thread to enter an infinite loop consuming ~100% CPU. An unauthenticated remote attacker can exploit this by opening a small number of crafted TCP connections to exhaust the entire worker thread pool, silently halting compilation services for all connected client JVMs.
