Discussion

Squid Web Proxy Cache Denial of Service Vulnerabilty

Squid Web Proxy Cache is a free, open source proxy server.



A problem exists in the manner which Squid handles requests to make FTP directories on proxied services. An attacker who makes a specially crafted request via the Squid proxy will be able to cause a denial of service to the proxy.



If affected with a denial of service then Squid must be restarted to regain normal functionality.
