Scientific Linux Security Update : gnutls on SL6.x, SL7.x i386/x86_64 (20160107) (SLOTH)

Medium Nessus Plugin ID 87838

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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 applications linked to the GnuTLS library must be restarted.

Solution

Update the affected packages.
