RHEL 2.1 : openssl (RHSA-2004:119)
medium Nessus Plugin ID 12479
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.
