Synopsis:	Moderate: openssl security update
Issue date:	2007-10-22
CVE Names:	CVE-2007-3108 CVE-2007-5135

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.
