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" |
