Ubuntu Security Notice USN-84-1

squid vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 4.10
Details
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)
