RHEL 2.1 / 3 : ruby (RHSA-2004:635)

Medium Nessus Plugin ID 15945


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


An updated ruby package that fixes a denial of service issue for the CGI instance is now available.

[Updated 17 Jan 2005] Errata has been updated to include 32-bit libraries on 64-bit architectures.

Ruby is an interpreted scripting language for object-oriented programming.

A flaw was dicovered in the CGI module of Ruby. If empty data is sent by the POST method to the CGI script which requires MIME type multipart/form-data, it can get stuck in a loop. A remote attacker could trigger this flaw and cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0983 to this issue.

Users are advised to upgrade to this erratum package, which contains a backported patch to cgi.rb.


Update the affected packages.
