Background ========== Webmin is a web-based interface for Unix-like systems. Usermin is a simplified version of Webmin designed for use by normal users rather than system administrators.

Impact ====== A non-authenticated user can read any file on the server using a specially crafted URL. Workaround ========== For a temporary workaround, IP Access Control can be setup on Webmin and Usermin. Resolution ========== All Webmin users should update to the latest stable version: # emerge --sync # emerge --ask --verbose --oneshot ">=app-admin/webmin-1.290" All Usermin users should update to the latest stable version: # emerge --sync # emerge --ask --verbose --oneshot ">=app-admin/usermin-1.220" References ========== [ 1 ] CVE-2006-3392 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3392 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-11.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.
