Synopsis
=======

Multiple vulnerabilities have been discovered in nfs-utils that could lead to a Denial of Service, or the execution of arbitrary code.

Background
=========

nfs-utils is a package containing the client and daemon implementations for the NFS protocol.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-fs/nfs-utils < 1.0.6-r6 >= 1.0.6-r6

Description
==========

Arjan van de Ven has discovered a buffer overflow on 64-bit architectures in 'rquota_server.c' of nfs-utils (CAN-2004-0946). A remotely exploitable flaw on all architectures also exists in the 'statd.c' file of nfs-utils (CAN-2004-1014), which can be triggered by a mishandled SIGPIPE.

Impact
=====

A remote attacker could potentially cause a Denial of Service, or even execute arbitrary code (64-bit architectures only) on a remote NFS server.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All nfs-utils users should upgarde to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.0.6-r6"
