Amazon Linux 1 Security Advisory: ALAS-2014-429
Advisory Release Date: 2014-10-16 22:14 Pacific
Advisory Updated Date: 2014-10-16 22:21 Pacific
Severity: Important

Issue Overview:

A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. This flaw allows a man-in-the-middle (MITM) attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections.
