Discussion

Netfilter Connection Tracking Denial of Service Vulnerability

A fix for a denial of service vulnerability has been reported by the Netfilter project. Linux 2.4.20 systems with kernels built supporting the CONFIG_IP_NF_CONNTRACK option or with the ip_conntrack module loaded are vulnerable. Other kernel versions are not affected. The vulnerability is due to the introduction into the Linux 2.4.20 kernel of a new generic linked list implementation. The reliance on the previous linked list implementation resulted in a condition which could result in a denial of service.
