Red Hat Security Advisory 2014-1246-01
Posted Sep 16, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1246-01 - Network Security Services 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 False Start was implemented in NSS. An attacker could use this flaw to potentially return unencrypted information from the server. A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application.
