Mandrakelinux Security Update Advisory
_______________________________________________________________________

Package name: ipsec-tools
Advisory ID: MDKSA-2004:027
Date: April 8th, 2004

Affected versions: 10.0
______________________________________________________________________

Problem Description:

A very serious security flaw was discovered by Ralf Spenneberg in
racoon, the IKE daemon of the KAME-tools. Racoon does not very the RSA
signature during phase one of a connection using either main or
aggressive mode. Only the certificate of the client is verified, the
certificate is not used to verify the client's signature.

All versions of ipsec-tools prior to 0.2.5 and 0.3rc5 are vulnerable
to this issue. The provided package updates ipsec-tools to 0.2.5.
