Red Hat Security Advisory

 

Synopsis: Moderate: openssl security update

Advisory ID: RHSA-2010:0054-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0054.html

Issue date: 2010-01-19

CVE Names: CVE-2009-2409 CVE-2009-4355

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

 

1. Summary:

 

Updated openssl packages that fix two security issues are now available for

Red Hat Enterprise Linux 5.

 

This update has been rated as having moderate security impact by the Red

Hat Security Response Team.

 

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 found that the OpenSSL library did not properly re-initialize its

internal state in the SSL_library_init() function after previous calls to

the CRYPTO_cleanup_all_ex_data() function, which would cause a memory leak

for each subsequent SSL connection. This flaw could cause server

applications that call those functions during reload, such as a combination

of the Apache HTTP Server, mod_ssl, PHP, and cURL, to consume all available

memory, resulting in a denial of service. (CVE-2009-4355)

 

Dan Kaminsky found that browsers could accept certificates with MD2 hash

signatures, even though MD2 is no longer considered a cryptographically

strong algorithm. This could make it easier for an attacker to create a

malicious certificate that would be treated as trusted by a browser.

OpenSSL now disables the use of the MD2 algorithm inside signatures by

default. (CVE-2009-2409)

 

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 that all previously-released

errata relevant to your system have been applied.

 

This update is available via Red Hat Network. Details on how to use

the Red Hat Network to apply this update are available at

http://kbase.redhat.com/faq/docs/DOC-11259

 

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

 

510197 - CVE-2009-2409 deprecate MD2 in SSL cert validation (Kaminsky)

546707 - CVE-2009-4355 openssl significant memory leak in certain SSLv3 requests (DoS)
