		Enea Security Advisory
Product: GnuTLS
Severity: Critical
Issue date: 2014-10-20
CVE Name: CVE-2014-3566, SSLv3 POODLE vulnerability

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue. This vulnerability can be exploited when TLS clients use a non-standard insecure protocol negotiation (it mostly affects browsers).

GnuTLS Clients should perform the standard TLS handshake as documented by GnuTLS to avoid this vulnerability.
