GLSA-200903-06 : nfs-utils: Access restriction bypass

high Nessus Plugin ID 35796

Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-200903-06 (nfs-utils: Access restriction bypass)

Michele Marcionelli reported that nfs-utils invokes the hosts_ctl() function with the wrong order of arguments, which causes TCP Wrappers to ignore netgroups.
Impact :

A remote attacker could bypass intended access restrictions, i.e. NFS netgroups, and gain access to restricted services.
Workaround :

There is no known workaround at this time.

Solution

All nfs-utils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-fs/nfs-utils-1.1.3'
