In Eclipse OpenJ9 versions up to 0.63.0, the JITServer component is vulnerable to denial of service due to improper boundary checks during protocol message and reply handling. An unauthenticated remote attacker or malicious JITServer can transmit malformed network payloads that cause out-of-bounds heap reads, immediately crashing the JITServer daemon or client JVM process via a segmentation fault (SIGSEGV).
