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,

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.
