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"
