Gentoo Linux Security Advisory

Title: Squid: Denial of Service (GLSA 200703-27)
Severity: low
Exploitable: remote
Date: March 31, 2007
Bug(s): #171681
ID: 200703-27

Synopsis

Squid is affected by a Denial of Service vulnerability.

Background

Squid is a multi-protocol proxy server.

Affected Packages

Package: net-proxy/squid
Vulnerable: < 2.6.12
Unaffected: >= 2.6.12
Architectures: All supported architectures


Description

Squid incorrectly handles TRACE requests that contain a "Max-Forwards" header field with value "0" in the clientProcessRequest() function.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All Squid users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.12"
