Side-channel Timing Attack

OpenSSL is vulnerable to side-channel timing attacks. These attacks are possible because the Montgomery ladder implementation doesn't run swap operations in constant time which makes it easier for local users to obtain ECDSA nonce values...

USN-3179-1 openjdk-8 vulnerabilities

Karthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES ciphers were vulnerable to birthday attacks. A remote attacker could possibly use this flaw to obtain clear text data from long encrypted sessions. This update moves those algorithms to the legacy algorithm set and causes...

OpenJDK: incorrect ECDSA signature extraction from the DER input (Libraries, 8168714)

It was discovered that the Libraries component of OpenJDK accepted ECDSA signatures using non-canonical DER encoding. This could cause a Java application to accept signature in an incorrect format not accepted by other cryptographic tools...
