RHSA-2005:543 - Security Advisory

Topic

Updated ruby packages that fix an arbitrary command execution issue are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

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

A bug was found in the way Ruby launched an XMLRPC server. If an XMLRPC
server is launched in a certain way, it becomes possible for a remote
attacker to execute arbitrary commands within the XMLRPC server. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-1992 to this issue.

Users of Ruby should update to these erratum packages, which contain a
backported patch and are not vulnerable to this issue.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. 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.
