Squid 3.5.x < 3.5.9 Multiple DoS

high Nessus Network Monitor Plugin ID 8952

Synopsis

The remote proxy server is affected by multiple Denial of Service vulnerabilities.

Description

Versions of Squid 3.5.x prior to 3.5.9 are potentially affected by by the following vulnerabilities :

- A denial of service vulnerability exists in file 'bio.cc' when handling hello messages. A remote attacker can exploit this to cause an infinite loop.
- An integer overflow condition exists in file 'bio.cc' due to improper validation of user-supplied input. A remote attacker can exploit this to crash the proxy, resulting in a denial of service.

Solution

Either upgrade to Squid version 3.5.9 or later, or apply the vendor-supplied patch.
