GLSA-200703-27 : Squid: Denial of Service
Medium Nessus Plugin ID 24932
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200703-27 (Squid: Denial of Service)
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.
SolutionAll Squid users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-proxy/squid-2.6.12'
