bouncycastle: TLS CBC padding timing attack

It was discovered that bouncycastle leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle...

Critical: openssl

Issue Overview: The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers ...
