Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : vm-builder vulnerability (USN-670-1)

high Nessus Plugin ID 37886

Synopsis

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

Description

Mathias Gug discovered that vm-builder improperly set the root password when creating virtual machines. An attacker could exploit this to gain root privileges to the virtual machine by using a predictable password.

This vulnerability only affects virtual machines created with vm-builder under Ubuntu 8.10, and does not affect native Ubuntu installations. An update was made to the shadow package to detect vulnerable systems and disable password authentication for the root account. Vulnerable virtual machines which an attacker has access to should be considered compromised, and appropriate actions taken to secure the machine.

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.
