descriptionThe remote host is affected by the vulnerability described in GLSA-200502-12 (Webmin: Information leak in Gentoo binary package) Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that the Webmin ebuild contains a design flaw. It imports the encrypted local root password into the miniserv.users file before building binary packages that include this file. Impact : A remote attacker could retrieve Portage-built Webmin binary packages and recover the encrypted root password from the build host. Workaround : Users who never built or shared a Webmin binary package are unaffected by this.
