Detail
| The connection tracking core of Netfilter for Linux 2.4.20, with CONFIG_IP_NF_CONNTRACK enabled or the ip_conntrack module loaded, allows remote attackers to cause a denial of service (resource consumption) due to an inconsistency with Linux 2.4.20's support of linked lists, which causes Netfilter to fail to identify connections with an UNCONFIRMED status and use large timeouts. |

| Id | Description |
|---|---|
| 6061 | Linux IPTables / Netfilter Connection Tracking Linked List DoS The netfilter (iptables) module of the Linux kernel contains a flaw that may allow a remote denial of service. The issue is triggered only when the connection tracking module ip_conntrack is loaded. When a large number of packets are sent to a machine so configured, one-way traffic packets are marked incorrectly as UNCONFIRMED statein the linked list, and assigned a very high timeout. This eventually consumes large amounts of system memory, and will result in loss of availability for the platform. |
