RHSA-2004:308 - Security Advisory

Topic

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

Description

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 CAN-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.
