Overview

openjdk-jre is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).

Affected versions of this package are vulnerable to Access Restriction Bypass. A flaw was found in the way the ForkJoinPool class in the Libraries component of OpenJDK handled its access control context. This could possibly lead to code being executed with incorrect permissions, possibly leading to bypass of certain intended restrictions defined by a SecurityManager.

Remediation

Upgrade openjdk-jre to version 8.0.251, 11.0.7, 14.0.1 or higher.
