1. Summary:

Updated OpenSSL packages that correct a security issue and various bugs are
now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, and is also a
full-strength general-purpose cryptography library.

A flaw was found in the SSL_get_shared_ciphers() utility function. An
attacker could send a list of ciphers to an application that used this
function and overrun a buffer by a single byte (CVE-2007-5135). Few
applications make use of this vulnerable function and generally it is used
only when applications are compiled for debugging. 

A number of possible side-channel attacks were discovered affecting
OpenSSL. A local attacker could possibly obtain RSA private keys being used
on a system. In practice these attacks would be difficult to perform
outside of a lab environment. This update contains backported patches to
mitigate these issues. (CVE-2007-3108)

As well, these updated packages fix the following bugs:

* multithreaded applications could cause a segmentation fault or deadlock
when calling the random number generator initialization (RAND_poll) in the
OpenSSL library, for a large number of threads simultaneously.

* in certain circumstances, if an application using the OpenSSL library
reused the SSL session cache for multiple purposes (with various parameters
of the SSL protocol), the session parameters could be mismatched.

* a segmentation fault could occur when a corrupted pkcs12 file was being
loaded using the "openssl pkcs12 -in [pkcs12-file]" command, where
[pkcs12-file] is the pkcs12 file.

Users of OpenSSL should upgrade to these updated packages, which contain
backported patches to resolve these issues.

Note: After installing this update, users are advised to either restart all
services that use OpenSSL or restart their system.

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/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

236164 - openssl RAND_poll segfault when fd >= FD_SETSIZE (affects apache2 startup with many SSL vhosts)
245083 - openssl crashes on pkcs12 file
245732 - CVE-2007-3108 RSA side-channel attack
250573 - CVE-NONE openssl branch prediction attacks
309801 - CVE-2007-5135 openssl SSL_get_shared_ciphers() off-by-one
