Detail

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS Ubuntu 8.10

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 6.06 LTS:
nfs-kernel-server 1:1.0.7-3ubuntu2.1

Ubuntu 7.10:
nfs-kernel-server 1:1.1.1~git-20070709-3ubuntu1.1

Ubuntu 8.04 LTS:
nfs-kernel-server 1:1.1.2-2ubuntu2.2

Ubuntu 8.10:
nfs-kernel-server 1:1.1.2-4ubuntu1.1

After a standard system upgrade you need to restart nfs services to effect the necessary changes.

Details follow:

It was discovered that nfs-utils did not properly enforce netgroup restrictions when using TCP Wrappers. Remote attackers could bypass the netgroup restrictions enabled by the administrator and possibly gain access to sensitive information.
