When parsing the configuration file, squid interpreted empty Access Control Lists (ACLs) without defined authentication schemes in a non-obvious way. This could allow remote attackers to bypass intended ACLs. (CAN-2005-0194)
A remote Denial of Service vulnerability was discovered in the domain name resolution code. A faulty or malicious DNS server could stop the Squid server immediately by sending a malformed IP address.
(CAN-2005-0446).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
