CentOS Errata and Security Advisory CESA-2016:0012
The GnuTLS library provides support for cryptographic algorithms and for
protocols such as Transport Layer Security (TLS).
A flaw was found in the way TLS 1.2 could use the MD5 hash function for
signing ServerKeyExchange and Client Authentication packets during a TLS
handshake. A man-in-the-middle attacker able to force a TLS connection to
use the MD5 hash function could use this flaw to conduct collision attacks
to impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575)
All gnutls users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For the update to take
effect, all applications linked to the GnuTLS library must be restarted.
