Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           ipsec-tools
 Advisory ID:            MDKSA-2004:069
 Date:                   July 14th, 2004

 Affected versions:	 10.0
 ______________________________________________________________________

 Problem Description:

 A vulnerability in racoon prior to version 20040408a would allow a
 remote attacker to cause a DoS (memory consumption) via an ISAKMP
 packet with a large length field.
 
 Another vulnerability in racoon was discovered where, when using RSA
 signatures, racoon would validate the X.509 certificate but would not
 validate the signature.  This can be exploited by an attacker sending
 a valid and trusted X.509 certificate and any private key.  Using this,
 they could perform a man-in-the-middle attack and initiate an
 unauthorized connection.  This has been fixed in ipsec-tools 0.3.3.
 
 The updated packages contain patches backported from 0.3.3 to correct
 the problem.
