3. Problem description:
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.
Testing performed by the OpenSSL group using the Codenomicon TLS Test Tool uncovered a bug in older versions of OpenSSL 0.9.6 prior to 0.9.6d that can lead to a denial of service attack (infinite loop). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0081 to this issue.
Testing performed by Novell using a test suite provided by NISCC uncovered an issue in the ASN.1 parser in versions of OpenSSL 0.9.6 prior to 0.9.6l which could cause large recursion and possibly lead to a denial of service attack if used where stack space is limited. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0851 to this issue.
These updated packages contain patches provided by the OpenSSL group that protect against these issues.
NOTE: Because server applications are affected by this issue, users are advised to either restart all services using OpenSSL functionality or restart their system after installing these updated packages.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website:
https://rhn.redhat.com/help/latest-up2date.pxt
