-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openssl security update Advisory ID: RHSA-2014:1053-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1053.html Issue date: 2014-08-13 CVE Names: CVE-2014-0221 CVE-2014-3505 CVE-2014-3506 CVE-2014-3508 CVE-2014-3510 ===================================================================== 1. Summary: Updated openssl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. Red Hat Product Security 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, 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. It was discovered that the OBJ_obj2txt() function could fail to properly NUL-terminate its output. This could possibly cause an application using OpenSSL functions to format fields of X.509 certificates to disclose portions of its memory. (CVE-2014-3508) Multiple flaws were discovered in the way OpenSSL handled DTLS packets. A remote attacker could use these flaws to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory. (CVE-2014-0221, CVE-2014-3505, CVE-2014-3506) A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman (DH) key exchange. A malicious server could cause a DTLS client using OpenSSL to crash if that client had anonymous DH cipher suites enabled. (CVE-2014-3510) Red Hat would like to thank the OpenSSL project for reporting CVE-2014-0221. Upstream acknowledges Imre Rad of Search-Lab as the original reporter of this issue. All OpenSSL users are advised to upgrade to these updated packages, which contain backported patches to correct these 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. Bugs fixed (https://bugzilla.redhat.com/): 1103593 - CVE-2014-0221 openssl: DoS when sending invalid DTLS handshake 1127490 - CVE-2014-3508 openssl: information leak in pretty printing functions 1127499 - CVE-2014-3505 openssl: DTLS packet processing double free 1127500 - CVE-2014-3506 openssl: DTLS memory exhaustion 1127503 - CVE-2014-3510 openssl: DTLS anonymous (EC)DH denial of service 6.
