                     Mandrakelinux Security Update Advisory
     _______________________________________________________________________

     Package name: squid
     Advisory ID: MDKSA-2004:025
     Date: March 30th, 2004

     Affected versions: 9.1, 9.2, 10.0, Corporate Server 2.1,
                             Multi Network Firewall 8.2
     ______________________________________________________________________

     Problem Description:

     A vulnerability was discovered in squid version 2.5.STABLE4 and
     earlier with the processing of %-encoded characters in a URL. If a
     squid configuration uses ACLs (Access Control Lists), it is possible
     for a remote attacker to create URLs that would not be properly tested
     against squid's ACLs, potentially allowing clients to access URLs that
     would otherwise be disallowed.
     
     As well, the provided packages for Mandrake Linux 9.2 and 9.1 include a
     new Access Control type called "urllogin" which can be used to protect
     vulnerable Microsoft Internet Explorer clients from accessing URLs that
     contain login information. While this Access Control type is available,
     it is not used in the default configuration.
     
     The updated packages are patched to protect against these
     vulnerabilities.
