Squid < 3.0STABLE23 / 3.1.x < 3.1.0.16 Remote DoS

Medium Nessus Network Monitor Plugin ID 5332

Synopsis

The remote host is vulnerable to a Denial of Service (Dos) attack.

Description

According to its banner, the version of Squid proxy caching server installed on the remote host is 2.x or 3.x earlier than 3.0.STABLE23 or 3.1.0.16. Such versions reportedly use incorrect data validation when processing specially crafted DNS packets. An attacker, exploiting this flaw, could cause a short term denial of service.

Solution

Either upgrade to Squid version 3.0.STABLE23 or 3.1.0.16 or later, or apply the patch referenced in the project's advisory above.
