-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: openssl security update Advisory ID: RHSA-2014:1692-01 Product: Red Hat Storage Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1692.html Issue date: 2014-10-22 CVE Names: CVE-2014-3513 CVE-2014-3567 ===================================================================== 1. Summary: Updated openssl packages that contain a backported patch to mitigate the CVE-2014-3566 issue and fix two security issues are now available for Red Hat Storage 2.1. Red Hat Product Security has rated this update as having Important 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. 2. Relevant releases/architectures: Red Hat Storage Server 2.1 - x86_64 3. Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram Transport Layer Security (DTLS) protocols, as well as a full-strength, general purpose cryptography library. This update adds support for the TLS Fallback Signaling Cipher Suite Value (TLS_FALLBACK_SCSV), which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol version fails. This can prevent a forceful downgrade of the communication to SSL 3.0. The SSL 3.0 protocol was found to be vulnerable to the padding oracle attack when using block cipher suites in cipher block chaining (CBC) mode. This issue is identified as CVE-2014-3566, and also known under the alias POODLE. This SSL 3.0 protocol flaw will not be addressed in a future update; it is recommended that users configure their applications to require at least TLS protocol version 1.0 for secure communication. For additional information about this flaw, see the Knowledgebase article at https://access.redhat.com/articles/1232123 A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure Real-time Transport Protocol (SRTP) extension data. A remote attacker could send multiple specially crafted handshake messages to exhaust all available memory of an SSL/TLS or DTLS server. (CVE-2014-3513) A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. (CVE-2014-3567) All OpenSSL users are advised to upgrade to these updated packages, which contain backported patches to mitigate the CVE-2014-3566 issue and correct the CVE-2014-3513 and CVE-2014-3567 issues. For the update to take effect, all services linked to the OpenSSL library (such as httpd and other SSL-enabled services) must be restarted or the system rebooted. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5.
