Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated openssl packages that fix two security issues are now available for Red Hat Enterprise Linux 5.The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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.
A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server code. A remote attacker could possibly use this flaw to change the ciphersuite associated with a cached session stored on the server, if the server enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option, possibly forcing the client to use a weaker ciphersuite after resuming the session. (CVE-2010-4180, CVE-2008-7270)
Note: With this update, setting the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option has no effect and this bug workaround can no longer be enabled.
All OpenSSL users should upgrade to these updated packages, which contain a backported patch to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.
Solution
Update the affected openssl, openssl-devel and / or openssl-perl packages.See Also
