Squid is affected by a Denial of Service vulnerability.
Squid is a multi-protocol proxy server.
Squid incorrectly handles TRACE requests that contain a "Max-Forwards" header field with value "0" in the clientProcessRequest() function.
A remote attacker can send specially crafted TRACE HTTP requests that will terminate the child process. A quickly repeated attack will lead to a Denial of Service.
There is no known workaround at this time.
All Squid users should upgrade to the latest version:
