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.

528f4677ccb5d5cb94823d6222c7de358ac0c637069400ec308261d6e1822ddbRed Hat Security Advisory 2014-0979-01 - The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: a subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. It was found that NSS accepted weak Diffie-Hellman Key exchange parameters. This could possibly lead to weak encryption being used in communication between the client and the server.

Netscape Portable Runtime provides platform independence for non-GUI operating system facilities. A race condition was found in the way NSS verified certain certificates. A remote attacker could use this flaw to crash an application using NSS or, possibly, execute arbitrary code with the privileges of the user running that application. 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.

If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Cody Crews discovered a method to bypass System Only Wrappers. If a user had enabled scripting, an attacker could potentially exploit this to steal confidential data or execute code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.

This update also addresses security issues in the bundled version of the NSS crypto library.
