Squid < 3.1.8 / 3.2.0.2 NULL Pointer Dereference Denial of Service

medium Nessus Plugin ID 49693

Language:

Synopsis

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

Description

According to its banner, the version of Squid is 3.x earlier than than 3.1.8, or 3.2.x earlier than 3.2.0.2. Such versions are potentially affected by a denial of service vulnerability caused by an internal error in string handling. A remote attacker, exploiting this flaw, could crash the affected service.

Note that Nessus has relied only on the version in the proxy server's banner, which is not updated by either of the patches the project has released to address the issue. If one of those has been applied properly and the service restarted, consider this to be a false positive.

Solution

Upgrade to Squid version 3.1.8 / 3.2.0.2 or later.
