CVSS v3.1

10

Critical

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Eclipse OpenJ9 versions up to and including 0.23
Description The issue is related to errors in handling UTF-8 encoded data. It may allow a remote attacker to execute arbitrary code. The problem occurs when the virtual machine or JNI natives are converting from UTF-8 characters to platform encoding, potentially leading to a stack-based buffer overflow.
Recommendations For Eclipse OpenJ9 versions up to and including 0.23, consider disabling the UTF-8 conversion functionality until a patch is available. Restrict access to the virtual machine or JNI natives to minimize the risk of exploitation. Avoid using the UTF-8 encoding in the affected virtual machine or JNI natives until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
