Vulnerability Assessment Details
Check for the version of the openssl packages
Detailed Explanation for this Vulnerability Assessment
Updated OpenSSL packages that fix various security issues are now
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.
OpenSSL contained a software work-around for a bug in SSL handling in
Microsoft Internet Explorer version 3.0.2. This work-around is enabled in
most servers that use OpenSSL to provide support for SSL and TLS. Yutaka
Oiwa discovered that this work-around could permit a possible hacker, acting as a
"man in the middle" to force an SSL connection to use SSL 2.0 rather than a
stronger protocol such as SSL 3.0 or TLS 1.0. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2969
to this issue.
A bug was also fixed in the way OpenSSL creates DSA signatures. A cache
timing attack was fixed in RHSA-2005-476 which caused OpenSSL to do private
key calculations with a fixed time window. The DSA fix for this was not
complete and the calculations are not always performed within a
fixed-window. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2005-0109 to this issue.
Users are advised to upgrade to these updated packages, which remove the
MISE 3.0.2 work-around and contain patches to correct these issues.
Note: After installing this update, users are advised to either
restart all services that use OpenSSL or restart their system.
