Scientific Linux Security Update : openssl on SL3.x i386/x86_64
Medium Nessus Plugin ID 60273
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA 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.
SolutionUpdate the affected openssl, openssl-devel and / or openssl-perl packages.
