description

Eclipse OpenJ9 JITServer protocol handling can mishandle message boundaries and terminate a JITServer daemon or connected client JVM. An unauthenticated attacker can cause denial of service by sending malformed traffic when they can reach a JITServer endpoint; a malicious JITServer can likewise affect its clients.

mitigation

Upgrade Eclipse OpenJ9 to version 0.63. Until upgrading, restrict JITServer network access to trusted hosts and networks.
