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

Vulnerability Assessment Summary
Squid: Multiple Denial of Service vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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

A possible hacker could attempt to retrieve a specially crafted URI via a
Squid server causing the service to crash. If a possible hacker 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.
