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 Signature Validation Bypass. A flaw was found in the way the Library component of OpenJDK handled JAR files containing multiple MANIFEST.MF files. Such JAR files could cause signature verification process to return an incorrect result, possibly allowing tampering with signed JAR files.
