New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.8
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated nss packages that fix one security issue are now available for Red Hat Enterprise Linux 4 Extended Life Cycle Support, Red Hat Enterprise Linux 5.6 Long Life, Red Hat Enterprise Linux 5.9 Extended Update Support, Red Hat Enterprise Linux 6.2 Advanced Update Support, and Red Hat Enterprise Linux 6.4 Extended Update Support.
Red Hat Product Security has rated this update as having Important 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. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.
A flaw was found in the way NSS parsed ASN.1 (Abstract Syntax Notation One) input from certain RSA signatures. A remote attacker could use this flaw to forge RSA certificates by providing a specially crafted signature to an application using NSS. (CVE-2014-1568)
Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Antoine Delignat-Lavaud and Intel Product Security Incident Response Team as the original reporters.
All NSS users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, applications using NSS must be restarted for this update to take effect.
SolutionUpdate the affected packages.
