Vulnerability Summary for CVE-2011-4108

Original release date: 01/05/2012
Last revised: 03/26/2014
Source: US-CERT/NIST

Overview

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack.
