CVE-2009-0115

Published: 30 March 2009

The Device Mapper multipathing driver (aka multipath-tools or device-mapper-multipath) 0.4.8, as used in SUSE openSUSE, SUSE Linux Enterprise Server (SLES), Fedora, and possibly other operating systems, uses world-writable permissions for the socket file (aka /var/run/multipathd.sock), which allows local users to send arbitrary commands to the multipath daemon.

Notes

AuthorNote
jdstrand
all versions of multipath-tools adjust the umask of the multipath
socket. In 9.04 and later this is 1000--set-umask-in-multipathd.patch. In
other releases the patch is applied inline.
the upstream patches are different, and can be found here:
