GLSA 201006-10: multipath-tools: World-writeable socket

http://security.gentoo.org/

Severity:	normal
Title:	multipath-tools: World-writeable socket
Date:	06/01/2010
Bugs:	#264564
ID:	201006-10

Synopsis

multipath-tools does not set correct permissions on the socket file, making it possible to send arbitrary commands to the multipath daemon for local users.

Background

multipath-tools are used to drive the Device Mapper multipathing driver.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
sys-fs/multipath-tools	< 0.4.8-r1	>= 0.4.8-r1	All supported architectures

Description

multipath-tools uses world-writable permissions for the socket file (/var/run/multipathd.sock).

Impact

Local users could send arbitrary commands to the multipath daemon, causing cluster failures and data loss.

Workaround

chmod o-rwx /var/run/multipath.sock

Resolution

All multipath-tools users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-fs/multipath-tools-0.4.8-r1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since November 13, 2009. It is likely that your system is already no longer affected by this issue.
