RHEL 2.1 / 3 / 4 : openssl (RHSA-2005:476)

This script is Copyright (C) 2005-2016 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated OpenSSL packages that fix security issues are now available.

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

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

Colin Percival reported a cache timing attack that could allow a
malicious local user to gain portions of cryptographic keys. The
Common Vulnerabilities and Exposures project (cve.mitre.org) assigned
the name CVE-2005-0109 to the issue. The OpenSSL library has been
patched to add a new fixed-window mod_exp implementation as default
for RSA, DSA, and DH private-key operations. This patch is designed to
mitigate cache timing and potentially related attacks.

A flaw was found in the way the der_chop script creates temporary
files. It is possible that a malicious local user could cause der_chop
to overwrite files (CVE-2004-0975). The der_chop script was deprecated
and has been removed from these updated packages. Red Hat Enterprise
Linux 4 did not ship der_chop and is therefore not vulnerable to this

Users are advised to update to these erratum packages which contain
patches to correct these issues.

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