RHSA-2006:0427 - Security Advisory

Topic

Updated ruby packages that fix a denial of service 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 creates its xmlrpc and http servers. The
servers use a non blocking socket, which enables a remote user to cause a
denial of service condition if they are able to transmit a large volume of
information from the network server. (CVE-2006-1931)

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.
