(Hylafax: Insecure temporary file creation in xferfaxstats script)

    Javier Fernandez-Sanguino has discovered that xferfaxstats cron script
    supplied by Hylafax insecurely creates temporary files with predictable
    filenames.
  
Impact :

    A local attacker could create symbolic links in the temporary file
    directory, pointing to a valid file somewhere on the filesystem. When
    the xferfaxstats script of Hylafax is executed, this would result in
    the file being overwritten with the rights of the user running the
    script, which typically is the root user.
  
Workaround :

    There is no known workaround at this time."
