Published: 2014-07-28 11:02:21
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Affected Versions:
nspr on CentOS 6

Technical Details:
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 race condition was found in the way NSS verified certain certificates. A remote attacker could use this flaw to crash an application using NSS or, possibly, execute arbitrary code with the privileges of the user running that application. (CVE-2014-1544) A flaw was found in the way TLS False Start was implemented in NSS. An attacker could use this flaw to potentially return unencrypted information from the server. (CVE-2013-1740) A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application. (CVE-2014-1490) It was found that NSS accepted weak Diffie-Hellman Key exchange (DHKE) parameters. This could possibly lead to weak encryption being used in communication between the client and the server. (CVE-2014-1491) An out-of-bounds write flaw was found in NSPR. A remote attacker could potentially use this flaw to crash an application using NSPR or, possibly, execute arbitrary code with the privileges of the user running that application. This NSPR flaw was not exposed to web content in any shipped version of Firefox. (CVE-2014-1545) 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. (CVE-2014-1492) Red Hat would like to thank the Mozilla project for reporting the CVE-2014-1544, CVE-2014-1490, CVE-2014-1491, and CVE-2014-1545 issues. Upstream acknowledges Tyson Smith and Jesse Schwartzentruber as the original reporters of CVE-2014-1544, Brian Smith as the original reporter of CVE-2014-1490, Antoine Delignat-Lavaud and Karthikeyan Bhargavan as the original reporters of CVE-2014-1491, and Abhishek Arya as the original reporter of CVE-2014-1545. In addition, the nss Linux Distribution Package has been upgraded to upstream version 3.16.1, and the nspr Linux Distribution Package has been upgraded to upstream version 4.10.6. These updated Linux Distribution Packages provide a number of bug fixes and enhancements over the previous versions. (BZ#1112136, BZ#1112135) Users of NSS and NSPR are advised to upgrade to these updated Linux Distribution Packages, which correct these issues and add these enhancements. After installing this update, applications using NSS or NSPR must be restarted for this update to take effect.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Summary:
The remote host is missing an update for the 'nspr' Linux Distribution Package(s) announced via the referenced advisory.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
