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 leaked timing information when decrypting

TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites

were used. A remote attacker could possibly use this flaw to retrieve plain

text from the encrypted packets by using a TLS/SSL or DTLS server as a

padding oracle. (CVE-2013-0169)

 

A NULL pointer dereference flaw was found in the OCSP response verification

in OpenSSL. A malicious OCSP server could use this flaw to crash

applications performing OCSP verification by sending a specially-crafted

response. (CVE-2013-0166)

 

It was discovered that the TLS/SSL protocol could leak information about

plain text when optional compression was used. An attacker able to control

part of the plain text sent over an encrypted TLS/SSL connection could

possibly use this flaw to recover other portions of the plain text.

(CVE-2012-4929)

 

Note: This update disables zlib compression, which was previously enabled

in OpenSSL by default. Applications using OpenSSL now need to explicitly

enable zlib compression to use it.

 

It was found that OpenSSL read certain environment variables even when used

by a privileged (setuid or setgid) application. A local attacker could use

this flaw to escalate their privileges. No application shipped with Red Hat

Enterprise Linux 5 and 6 was affected by this problem. (BZ#839735)

 

All OpenSSL users should upgrade to these updated packages, which contain

backported patches to resolve 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.

 

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/knowledge/articles/11258

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

839735 - openssl: environment settings honored when used in privileged apps

857051 - CVE-2012-4929 SSL/TLS CRIME attack against HTTPS

907589 - CVE-2013-0169 SSL/TLS: CBC padding timing attack (lucky-13)

908052 - CVE-2013-0166 openssl: DoS due to improper handling of OCSP response verification
