Several remote vulnerabilities have been discovered in racoon, the Internet Key Exchange daemon of ipsec-tools. The The Common Vulnerabilities and Exposures project identified the following problems: Neil Kettle discovered a NULL pointer dereference on crafted fragmented packets that contain no payload. This results in the daemon crashing which can be used for denial of service attacks . Various memory leaks in the X.509 certificate authentication handling and the NAT-Traversal keepalive implementation can result in memory exhaustion and thus denial of service . For the oldstable distribution , this problem has been fixed in version 0.6.6-3.1etch3. For the stable distribution , this problem has been fixed in version 0.7.1-1.3+lenny2. For the testing distribution , this problem will be fixed soon. For the unstable distribution , this problem has been fixed in version 1:0.7.1-1.5. We recommend that you upgrade your ipsec-tools packages.
