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.
