CVE-2018-2618

First published: Mon Jan 15 2018(Updated: )

It was discovered that the DHKeyAgreement and P11KeyAgreement implementations in the JCE component of OpenJDK did not guarantee sufficient strength of used keys to adequately protect generated shared secret. This could make it easier to break encryption by attacking key agreement rather than the encryption using the negotiated key. The patch for this issue causes classes' method generateSecret(String algorithm) to fail unless it's call for "TlsPremasterSecret", or the "jdk.crypto.KeyAgreement.legacyKDF" system property is set to true.
