Background ========== multipath-tools are used to drive the Device Mapper multipathing driver. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-fs/multipath-tools < 0.4.8-r1 >= 0.4.8-r1 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. References ========== [ 1 ] CVE-2009-0115 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0115 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201006-10.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
