Multiple race conditions in the handling of O_DIRECT in Linux kernel prior to version 2.4.22 could cause stale data to be returned from the disk when handling sparse files, or cause incorrect data to be returned when a file is truncated as it is being read, which might allow local users to obtain sensitive data that was originally owned by other users, a different vulnerability than CVE-2003-0018.Show less

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.Show less
