A flaw was found in the way TLS 1.2 could use the MD5 hash function for

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)

contain a backported patch to correct this issue. For the update to take
