                Mandrake Linux Security Update Advisory

Package name:           squid
Date:                   July 25th, 2001
Advisory ID:            MDKSA-2001:066

Affected versions:      7.1, 7.2, 8.0, Corporate Server 1.0.1,
                        Single Network Firewall 7.2

Problem Description:

 The Squid proxy server has a serious security flaw in versions
 2.3.STABLE2 through 2.3.STABLE4.  This problem surfaces when Squid is
 used in httpd_accel mode.  If you configure httpaccelwith_proxy off
 then any request to Squid is allowed.  Malicious users may use your
 proxy to portscan remote systems, forge email, and other activities.


Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig package.rpm
You can get the GPG public key of the Mandrake Linux Security Team at
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
