Description
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to in the implementation of the shared cache (which is enabled by default in OpenJ9 builds) the size of a string is not properly checked against the size of the buffer. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
