What is CVE-2019-11772?

In Eclipse OpenJ9 prior to version 0.15, the method String.getBytes(int, int, byte[], int) is vulnerable due to a lack of verification for null byte arrays and index bounds during JIT compilation. This oversight permits attackers to perform arbitrary writes to any 32-bit address or beyond the limit of a byte array, posing significant risks when executing Java code under a SecurityManager. This vulnerability can lead to unauthorized access and manipulation of memory, feeding potential exploits if left unaddressed.

Affected Version(s)

Eclipse OpenJ9 < 0.15.0
