3. Description:

 

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)

and Transport Layer Security (TLS v1) protocols, as well as a

full-strength, general purpose cryptography library.

 

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 openssl 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 OpenSSL 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)
