3. Description:

Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications.

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 nss 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 services linked to the NSS library must be restarted, or the
system rebooted.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1289841 - CVE-2015-7575 TLS 1.2 Transcipt Collision attacks against MD5 in key exchange protocol (SLOTH)
