Synopsis

========

 

IPsec-Tools' racoon is affected by a remote Denial of Service

vulnerability.

 

Background

IPsec-Tools is a port of KAME's implementation of the IPsec utilities.

It contains a collection of network monitoring tools, including racoon,

ping, and ping6.

Description

===========

 

Two Denial of Service vulnerabilities have been reported in racoon:

 

* The vendor reported a memory leak in racoon/proposal.c that can be

triggered via invalid proposals (CVE-2008-3651).

 

* Krzysztof Piotr Oledzk reported that src/racoon/handler.c does not

remove an "orphaned ph1" (phase 1) handle when it has been initiated

remotely (CVE-2008-3652).

 

Impact

======

 

An attacker could exploit these vulnerabilities to cause a Denial of

Service.

 

Workaround

There is no known workaround at this time.
