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:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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.

It was discovered that OpenSSL would accept ephemeral RSA keys when using
non-export RSA cipher suites. A malicious server could make a TLS/SSL
client using OpenSSL use a weaker key exchange method. (CVE-2015-0204)

An integer underflow flaw, leading to a buffer overflow, was found in the
way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to
make an application using OpenSSL decode a specially crafted Base64-encoded
input (such as a PEM file) could use this flaw to cause the application to
crash. Note: this flaw is not exploitable via the TLS/SSL protocol because
the data being transferred is not Base64-encoded. (CVE-2015-0292)

A denial of service flaw was found in the way OpenSSL handled SSLv2
handshake messages. A remote attacker could use this flaw to cause a
TLS/SSL server using OpenSSL to exit on a failed assertion if it had both
the SSLv2 protocol and EXPORT-grade cipher suites enabled. (CVE-2015-0293)

Multiple flaws were found in the way OpenSSL parsed X.509 certificates.
An attacker could use these flaws to modify an X.509 certificate to produce
a certificate with a different fingerprint without invalidating its
signature, and possibly bypass fingerprint-based blacklisting in
applications. (CVE-2014-8275)

An out-of-bounds write flaw was found in the way OpenSSL reused certain
ASN.1 structures. A remote attacker could possibly use a specially crafted
ASN.1 structure that, when parsed by an application, would cause that
application to crash. (CVE-2015-0287)

A NULL pointer dereference flaw was found in OpenSSL's X.509 certificate
handling implementation. A specially crafted X.509 certificate could cause
an application using OpenSSL to crash if the application attempted to
convert the certificate to a certificate request. (CVE-2015-0288)

A NULL pointer dereference was found in the way OpenSSL handled certain
PKCS#7 inputs. An attacker able to make an application using OpenSSL
verify, decrypt, or parse a specially crafted PKCS#7 input could cause that
application to crash. TLS/SSL clients and servers using OpenSSL were not
affected by this flaw. (CVE-2015-0289)

Red Hat would like to thank the OpenSSL project for reporting 
CVE-2015-0287, CVE-2015-0288, CVE-2015-0289, CVE-2015-0292, and 
CVE-2015-0293. Upstream acknowledges Emilia KÃ¤sper of the OpenSSL 
development team as the original reporter of CVE-2015-0287, Brian Carpenter
as the original reporter of CVE-2015-0288, Michal Zalewski of Google as the
original reporter of CVE-2015-0289, Robert Dugal and David Ramos as the 
original reporters of CVE-2015-0292, and Sean Burford of Google and Emilia 
KÃ¤sper of the OpenSSL development team as the original reporters of 
CVE-2015-0293.

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 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.
