Description Mark J. Cox 2004-04-07 11:22:57 UTC
With versions of ipsec-tools prior to 0.2.3, it was possible for an
attacker to cause unauthorized deletion of SA (Security Associations.)
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0164 to this issue.

With versions of ipsec-tools prior to 0.2.5, the RSA signature on
x.509 certificates was not properly verified when using certificate
based authentication. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0155 to this issue.

This issue affected Red Hat Enterprise Linux 3

RHSA-2004:165 in progress

Comment 1 Mark J. Cox 2004-04-14 18:58:51 UTC
Additionally:

When ipsec-tools receives an ISAKMP header, it will attempt
to allocate sufficient memory for the entire ISAKMP message
according to the header's length field. If an attacker crafts
an ISAKMP header with a extremely large value in the length
field, racoon may exceed operating system resource limits and
be terminated, resulting in a denial of service. CAN-2004-0403
