Critical Nessus Plugin ID 68023

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: 6.7

Synopsis

The remote Oracle Linux host is missing a security update.

Description

From Red Hat Security Advisory 2010:0173 :

Updated openssl096b packages that fix one security issue are now available for Red Hat Enterprise Linux 3 and 4.

The Red Hat Security Response Team 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.

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.

It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could cause an application using the OpenSSL library to crash or, possibly, execute arbitrary code.
(CVE-2009-3245)

All openssl096b users should upgrade to these updated packages, which contain a backported patch to resolve this issue. For the update to take effect, all programs using the openssl096b library must be restarted.

Solution

Update the affected openssl096b package.
