(Webmin, Usermin: Multiple vulnerabilities in Usermin)

    There is an input validation bug in the webmail feature of Usermin.
    Additionally, the Webmin and Usermin installation scripts write to
    /tmp/.webmin without properly checking if it exists first.
  
Impact :

    The first vulnerability allows a remote attacker to inject arbitrary
    shell code in a specially crafted e-mail. This could lead to remote
    code execution with the privileges of the user running Webmin or
    Usermin.
    The second could allow local users who know Webmin or Usermin is going
    to be installed to have arbitrary files be overwritten by creating a
    symlink by the name /tmp/.webmin that points to some target file, e.g.
    /etc/passwd.
  
Workaround :

    There is no known workaround at this time."
