Red Hat Security Advisory 2017-2832-01 - Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Security Fix: A use-after-free flaw was found in the TLS 1.2 implementation in the NSS library when client authentication was used. A malicious client could use this flaw to cause an application compiled against NSS to crash or, potentially, execute arbitrary code with the permission of the user running the application.
