Backport security fix for %00 hole.

Fedora Update Notification

Name : squid Version : 2.5.STABLE3 Release : 1.fc1 Summary : The Squid proxy caching server. Description : Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests.

Squid consists of a main server program squid, a Domain Name System lookup program (dnsserver), a program for retrieving FTP data (ftpget), and some management and client tools.

--------------------------------------------------------------------- Update Information:

--------------------------------------------------------------------- * Tue Mar 09 2004 Jay Fenlason 7:2.5.STABLE3-1.fc1

- Backport security fix for %00 hole. See CAN-2004-0189: The "%xx" URL decoding function in Squid 2.5STABLE4 and earlier allows remote attackers to bypass url_regex ACLs via a URL with a NULL ("%00") characterm, which causes Squid to use only a portion of the requested URL when comparing it against the access control lists. - Backport security fix that adds urllogin acl type that can be used to protect vulnerable Microsoft Internet Explorer clients.
