    The Gentoo Linux Security Audit Team discovered that the sandbox
    utility was vulnerable to multiple TOCTOU (Time of Check, Time of Use)
    file creation race conditions.
  
Impact :

    Local users may be able to create or overwrite arbitrary files with the
    permissions of the root user.
  
Workaround :

    There is no known workaround at this time."
