Red Hat Security Advisory 2014-1053-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer, Transport Layer Security, and Datagram Transport Layer Security 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. 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.

=====================================================================

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
