Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for nss is now available for Red Hat Enterprise Linux 6 and
Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Network Security Services (NSS) is a set of libraries designed to
support the cross-platform development of security-enabled client and
server applications.

Security Fix(es) :

* 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. (CVE-2017-7805)

Red Hat would like to thank the Mozilla project for reporting this
issue. Upstream acknowledges Martin Thomson as the original reporter.
