Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : nfs-utils vulnerability (USN-687-1)

High Nessus Plugin ID 36927


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


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.

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.


Update the affected nfs-common, nfs-kernel-server and / or nhfsstone packages.
