(gettext: Insecure temporary file handling)

    gettext insecurely creates temporary files in world-writeable
    directories with predictable names.
  
Impact :

    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    gettext is called, this would result in file access with the rights of
    the user running the utility, which could be the root user.
  
Workaround :

    There is no known workaround at this time."
