(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."

    value:
"Webmin users should delete any old shared Webmin binary package as soon
    as possible. They should also consider their buildhost root password
    potentially exposed and follow proper audit procedures.
    If you plan to build binary packages, you should upgrade to the latest
    version:
    # emerge --sync
    # emerge --ask --oneshot --verbose '>=app-admin/webmin-1.170-r3'"
