Gentoo Linux Security Advisory

Title: multipath-tools: World-writeable socket (GLSA 201006-10)
Severity: normal
Exploitable: local
Date: June 01, 2010
Bug(s): #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: sys-fs/multipath-tools
Vulnerable: < 0.4.8-r1
Unaffected: >= 0.4.8-r1
Architectures: 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:
Code:
# 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.
