RHEL 4 : ruby (RHSA-2005:543)

critical Nessus Plugin ID 19390

Synopsis

The remote Red Hat host is missing a security update for ruby.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2005:543 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL ruby package based on the guidance in RHSA-2005:543.
