CVE-2021-2369

First published: Thu Jul 15 2021(Updated: )

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. After the fix, all JAR files with multiple MANIFEST.MF files are treated as unsigned.
