Mandrakelinux Security Update Advisory
Package name: ipsec-tools
Advisory ID: MDKSA-2004:069
Date: July 14th, 2004
Affected versions: 10.0
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.
To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you.
All packages are signed by Mandrakesoft for security. You can obtain the GPG public key of the Mandrakelinux Security Team by executing:
