GLSA-200701-22 : Squid: Multiple Denial of Service vulnerabilities

medium Nessus Plugin ID 24258


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200701-22 (Squid: Multiple Denial of Service vulnerabilities)

Squid fails to correctly handle ftp:// URI's. There is also an error in the external_acl queue which can cause an infinite looping condition.
Impact :

An attacker could attempt to retrieve a specially crafted URI via a Squid server causing the service to crash. If an attacker could generate a sufficiently high load on the Squid services, they could cause a Denial of Service by forcing Squid into an infinite loop.
Workaround :

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-2.6.7'
