http://security.gentoo.org/

Severity:	high
Title:	nfs-utils: Multiple remote vulnerabilities
Date:	12/14/2004
Bugs:	#72113
ID:	200412-08

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	Architecture(s)
net-fs/nfs-utils	< 1.0.6-r6	>= 1.0.6-r6	All supported architectures

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"
