Scientific Linux Security Update : openssl on SL4.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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.
