Gentoo Linux Security Advisory

Title: IPsec-Tools: racoon Denial of Service (GLSA 200812-03)
Severity: normal
Exploitable: remote
Date: December 02, 2008
Bug(s): #232831
ID: 200812-03

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.

Affected Packages

Package: net-firewall/ipsec-tools
Vulnerable: < 0.7.1
Unaffected: >= 0.7.1
Architectures: All supported architectures


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.

Resolution

All IPsec-Tools users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.7.1"
