The eay_check_x509cert function in KAME Racoon successfully verifies certificates even when OpenSSL validation fails, which could allow remote attackers to bypass authentication.

The remote host is missing Apple's Security Update 2004-09-07. This security update fixes the following components: CoreFoundation, IPSec, Kerberos, libpcap, lukemftpd, NetworkConfig, OpenLDAP, OpenSSH, PPPDialer, rsync, Safari and tcpdump

The remote host is missing Security Update 2004-09-07.  This security update fixes the following components :

  - CoreFoundation
  - IPSec
  - Kerberos
  - libpcap
  - lukemftpd
  - NetworkConfig
  - OpenLDAP
  - OpenSSH
  - PPPDialer
  - rsync
  - Safari
  - tcpdump

These applications contain multiple vulnerabilities that may allow a remote attacker to execute arbitrary code.

The remote host is affected by the vulnerability described in GLSA-200406-17 (IPsec-Tools: authentication bug in racoon)

    The KAME IKE daemon racoon is used to authenticate peers during Phase 1     when using either preshared keys, GSS-API, or RSA signatures. When     using RSA signatures racoon validates the X.509 certificate but not the     RSA signature.
  Impact :

    By sending a valid and trusted X.509 certificate and any private key an     attacker could exploit this vulnerability to perform man-in-the-middle     attacks and initiate unauthorized connections.
  Workaround :

    There is no known workaround at this time. All users are encouraged to     upgrade to the latest available version.

An updated ipsec-tools package that fixes verification of X.509 certificates in racoon is now available.

IPSEC uses strong cryptography to provide both authentication and encryption services.

When configured to use X.509 certificates to authenticate remote hosts, ipsec-tools versions 0.3.3 and earlier will attempt to verify that host certificate, but will not abort the key exchange if verification fails. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0607 to this issue.

Users of ipsec-tools should upgrade to this updated package which contains a backported security patch and is not vulnerable to this issue.
