Detail
| Problem Description: An updated ruby package that fixes a denial of service issue for the CGI instance is now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: 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 CAN-2004-0983 to this issue. Users are advised to upgrade to this erratum package, which contains a backported patch to cgi.rb. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5.
