Severity: Normal Title: nfs-utils: Access restriction bypass Date: March 07, 2009 Bugs: #242696 ID: 200903-06

Synopsis ========
An error in nfs-utils allows for bypass of the netgroups restriction.
Background ==========
nfs-utils contains the client and daemon implementations for the NFS protocol.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/nfs-utils < 1.1.3 >= 1.1.3
Description ===========
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.
Resolution ==========
All nfs-utils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.1.3"
References ==========
