Description:
  Paul Nasrat has discovered a bug in squid's httpd_accel mode that
  allows users to use squid as a portscanner similar to ftp bounce
  scanning because squid does not properly use ACLs in the config file.
  Paul conjectures it may be possible to pass data through the squid
  proxy to communicate in a meaningful fashion, possibly bypassing
  network security settings.

  This update fixes this problem.
