ID: | 200703-27 |
Synopsis
Squid is affected by a Denial of Service vulnerability.Background
Squid is a multi-protocol proxy server.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
net-proxy/squid | < 2.6.12 | >= 2.6.12 | 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.12"
