"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.

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
