Synopsis :

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

Description :

Updated OpenSSL packages that fix a remote denial of service
vulnerability are now available for Red Hat Enterprise Linux 2.1.

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 CVE-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 CVE-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.
