CentOS Update for nspr CESA-2010:0165 centos5 i386

Published: 2011-08-09 06:20:34
CVE Author: NIST National Vulnerability Database

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

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

Affected Versions:
nspr on CentOS 5

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. Applications built with NSS can support SSLv2, SSLv3, TLS, and other security standards. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities. These facilities include threads, thread synchronization, normal file and network I/O, interval timing, calendar time, basic memory management (malloc and free), and shared library linking. A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746. (CVE-2009-3555) Refer to the referenced Knowledgebase article for additional details about this flaw. Users of Red Hat Certificate System 7.3 and 8.0 should review the referenced Knowledgebase article before installing this update. All users of NSS are advised to upgrade to these updated Linux Distribution Packages, which update NSS to version 3.12.6. This erratum also updates the NSPR Linux Distribution Packages to the version required by NSS 3.12.6. All running applications using the NSS library must be restarted for this update to take effect.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

Solution Type:

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".
