SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated nss, nss-util, and nss-softokn packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link 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. Applications built with NSS can support SSLv3, TLS, and other security standards.
It was found that the implementation of Internationalizing Domain Names in Applications (IDNA) hostname matching in NSS did not follow the RFC 6125 recommendations. This could lead to certain invalid certificates with international characters to be accepted as valid.
In addition, the nss, nss-util, and nss-softokn packages have been upgraded to upstream version 3.16.2, which provides a number of bug fixes and enhancements over the previous versions. (BZ#1124659)
Users of NSS are advised to upgrade to these updated packages, which correct these issues and add these enhancements. After installing this update, applications using NSS must be restarted for this update to take effect.
SolutionUpdate the affected nss, nss-softokn and / or nss-util packages.
