Medium Nessus Network Monitor Plugin ID 6931

Synopsis

The remote proxy server is affected by a denial of service vulnerability

Description

Squid version prior to 3.x to 3.2.12 or 3.3.x prior to 3.3.7 are potentially affected by a denial of service vulnerability. A buffer overflow exists in the 'idnsALookup' function in the file 'dns_internal.cc' that could allow specially crafted HTTP requests that could result in a denial of service

Solution

Either upgrade to Squid version 3.2.12 / 3.3.7 or later, or apply the vendor-supplied patch.
