An update for nss, nss-softokn, nss-util, and nspr is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.
The following packages have been upgraded to a later upstream version:
nss (3.44.0), nss-softokn (3.44.0), nss-util (3.44.0), nspr (4.21.0).
(BZ#1645231, BZ#1692269, BZ#1692271, BZ#1692274)
Security Fix(es) :
ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries (CVE-2018-0495)
nss: Cache side-channel variant of the Bleichenbacher attack (CVE-2018-12404)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
