CVE-2018-2579: Weak Encryption

First published: Sun Jan 14 2018(Updated: )

It was discovered that multiple encryption key classes (DESKey, DESedeKey, PBEKey, PBKDF2KeyImpl) in the crypto provider in the Libraries component of OpenJDK did not properly synchronize access to their internal key data from multiple threads. This could possibly cause a multi-threaded Java application to apply weak encryption to data because of use of key that was zeroed out during object finalization.
