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) 6.
