Scientific Linux Security Update : openssl on SL3.x i386/x86_64

Medium Nessus Plugin ID 60273

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: 5.8

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A flaw was found in the SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer with a single byte (CVE-2007-5135). Few applications make use of this vulnerable function and generally it is used only when applications are compiled for debugging.

A number of possible side-channel attacks were discovered affecting OpenSSL. A local attacker could possibly obtain RSA private keys being used on a system. In practice these attacks would be difficult to perform outside of a lab environment. This update contains backported patches designed to mitigate these issues. (CVE-2007-3108).

Note: After installing this update, users are advised to either restart all services that use OpenSSL or restart their system.

Solution

Update the affected openssl, openssl-devel and / or openssl-perl packages.
