The vulnerability is due to improper block cipher padding implemented in TLSv1 when using Cipher Block Chaining (CBC) mode. An attacker could exploit the vulnerability to perform an "oracle padding" side channel attack on the cryptographic message. A successful exploit could allow the attacker to access sensitive information. Consult the bug release note for additional information about affected products and configurations.
