Synopsis: Moderate: nss security update
Advisory ID: SLSA-2016:0007-1
Issue Date: 2016-01-07
CVE Numbers: CVE-2015-7575
--

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)

For the update to take effect, all services linked to the NSS library must
be restarted, or the system rebooted.
