Ubuntu 4.10 / 5.04 : ruby1.8 vulnerability (USN-146-1)

high Nessus Plugin ID 20540

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Nobuhiro IMAI discovered that the changed default value of the Module#public_instance_methods() method broke the security protection of XMLRPC server handlers. A remote attacker could exploit this to execute arbitrary commands on an XMLRPC server.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
