CentOS Update for openssl CESA-2014:0015 centos6

Published: 2014-01-10 06:17:59
CVE Author: NIST National Vulnerability Database

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

Affected Versions:
openssl on CentOS 6

Technical Details:
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A flaw was found in the way OpenSSL determined which hashing algorithm to use when TLS protocol version 1.2 was enabled. This could possibly cause OpenSSL to use an incorrect hashing algorithm, leading to a crash of an application using the library. (CVE-2013-6449) It was discovered that the Datagram Transport Layer Security (DTLS) protocol implementation in OpenSSL did not properly maintain encryption and digest contexts during renegotiation. A lost or discarded renegotiation handshake packet could cause a DTLS client or server using OpenSSL to crash. (CVE-2013-6450) A NULL pointer dereference flaw was found in the way OpenSSL handled TLS/SSL protocol handshake packets. A specially crafted handshake packet could cause a TLS/SSL client using OpenSSL to crash. (CVE-2013-4353) All OpenSSL users are advised to upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

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 'openssl' 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".
