Two problems have been found in the wget package as distributed in Debian GNU/Linux :

  • Stefano Zacchiroli found a buffer overrun in the url_filename function, which would make wget segfault on very long URLs
  • Steven M. Christey discovered that wget did not verify the FTP server response to a NLST command: it must not contain any directory information, since that can be used to make an FTP client overwrite arbitrary files.

Both problems have been fixed in version 1.5.3-3.1 for Debian GNU/Linux 2.2/potato and version 1.8.1-6.1 for Debian GNU/Linux 3.0/woody.
