CentOS Update for nss CESA-2016:0684 centos5

CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P
Detection Type:
Linux Distribution Package
Summary:
Check the version of nss
Detection Method:
Checks if a vulnerable version is present on the target host.
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.
The following Linux Distribution Packages have been upgraded to a newer upstream version: nss
3.21.0, nspr 4.11.0. (BZ#1297944, BZ#1297943)
Security Fix(es):
* A use-after-free flaw was found in the way NSS handled DHE
(Diffie-Hellman key exchange) and ECDHE (Elliptic Curve Diffie-Hellman key
exchange) handshake messages. A remote attacker could send a specially
crafted handshake message that, when parsed by an application linked
against NSS, would cause that application to crash or, under certain
special conditions, execute arbitrary code using the permissions of the
user running the application. (CVE-2016-1978)
* A use-after-free flaw was found in the way NSS processed certain DER
(Distinguished Encoding Rules) encoded cryptographic keys. An attacker
could use this flaw to create a specially crafted DER encoded certificate
which, when parsed by an application compiled against the NSS library,
could cause that application to crash, or execute arbitrary code using the
permissions of the user running the application. (CVE-2016-1979)
Red Hat would like to thank the Mozilla project for reporting these issues.

What's vulnerability management?
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".
