Linux Advisory Watch Thank you for reading the Linux Advisory Watch Security Newsletter. The purpose of this document is to provide our readers with a quick summary of each week's vendor security bulletins and pointers on methods to improve the security posture of your open source system. Vulnerabilities affect nearly every vendor virtually every week, so be sure to read through to find the updates your distributor have made available.

LinuxSecurity.com Feature Extras:

Squid and Digest Authentication - Digest AuthenticationDigest Authentication hashes the password before transmitting over the wire. Essentially it sends a message digest generated from multiple items including username, realm and nonce value. If you want to know more see (RFC 2617).

Squid and Basic Authentication - This is perhaps the easiest authentication helper to configure in Squid, but also the most insecure. The biggest problem with Basic is it transmits username and password in clear text, hence very susceptible to network sniffing or man in the middle type attacks. The only reason I'm writing about it is it's a valid authentication mechanism in some limited circumstances. Secondly I want to show you how authentication has evolved over the years.
