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 services linked to the NSS library must be restarted, or the system rebooted. -- SL6 x86_64 nss-3.19.1-8.el6_7.i686.rpm nss-3.19.1-8.el6_7.x86_64.rpm nss-debuginfo-3.19.1-8.el6_7.i686.rpm nss-debuginfo-3.19.1-8.el6_7.x86_64.rpm nss-sysinit-3.19.1-8.el6_7.x86_64.rpm nss-tools-3.19.1-8.el6_7.x86_64.rpm nss-devel-3.19.1-8.el6_7.i686.rpm nss-devel-3.19.1-8.el6_7.x86_64.rpm nss-pkcs11-devel-3.19.1-8.el6_7.i686.rpm nss-pkcs11-devel-3.19.1-8.el6_7.x86_64.rpm i386 nss-3.19.1-8.el6_7.i686.rpm nss-debuginfo-3.19.1-8.el6_7.i686.rpm nss-sysinit-3.19.1-8.el6_7.i686.rpm nss-tools-3.19.1-8.el6_7.i686.rpm nss-devel-3.19.1-8.el6_7.i686.rpm nss-pkcs11-devel-3.19.1-8.el6_7.i686.rpm SL7 x86_64 nss-3.19.1-19.el7_2.i686.rpm nss-3.19.1-19.el7_2.x86_64.rpm nss-debuginfo-3.19.1-19.el7_2.i686.rpm nss-debuginfo-3.19.1-19.el7_2.x86_64.rpm nss-sysinit-3.19.1-19.el7_2.x86_64.rpm nss-tools-3.19.1-19.el7_2.x86_64.rpm nss-devel-3.19.1-19.el7_2.i686.rpm nss-devel-3.19.1-19.el7_2.x86_64.rpm nss-pkcs11-devel-3.19.1-19.el7_2.i686.rpm nss-pkcs11-devel-3.19.1-19.el7_2.x86_64.rpm - Scientific Linux Development Team
