Details

David Duncan Ross Palmer and Henrik Nordstrom discovered that squid
incorrectly handled special characters in FTP URLs. Remote users with
access to squid could crash the server leading to a denial of service.
(CVE-2007-0247)

Erick Dantas Rotole and Henrik Nordstrom discovered that squid could end
up in an endless loop when exhausted of available external ACL helpers.
Remote users with access to squid could cause CPU starvation, possibly
leading to a denial of service. This does not affect a default Ubuntu
installation, since external ACL helpers must be configured and used.
