Synopsis
The remote proxy server is affected by a denial of service vulnerability.Description
According to its banner, the version of Squid running on the remote host is 3.2.x prior to 3.2.13 or 3.3.x prior to 3.3.8. It is, therefore, affected by a denial of service vulnerability. The vulnerability exists when handling a port number in the host header of a specially crafted HTTP Request.Note that Nessus has relied only on the version in the proxy server's banner, which is not updated by the patch that the project has released to address this issue. If this patch has been applied properly and the service has been restarted, consider this to be a false positive.
Solution
Either upgrade to Squid version 3.2.13 / 3.3.8 or later, or apply the vendor-supplied patch.See Also
