|Gentoo Linux Security Advisory
Title: Squid: Denial of Service (GLSA 200703-27)
Date: March 31, 2007
Squid is affected by a Denial of Service vulnerability.
Squid is a multi-protocol proxy server.
Vulnerable: < 2.6.12
Unaffected: >= 2.6.12
Architectures: All supported architectures
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:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.12"
