|---|---|---|---|---|---|---|---|---|
| CVE-2021-3773 | Cri | 0.64 | 9.8 | 0.05 | Feb 16, 2022 | A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint information for further use in traditional network attacks. | ||
| CVE-2023-6040 | Hig | 0.51 | 7.8 | 0.00 | Jan 12, 2024 | An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within… | ||
| CVE-2002-0704 | Hig | 0.49 | 7.5 | 0.03 | Jul 26, 2002 | The Network Address Translation (NAT) capability for Netfilter ("iptables") 1.2.6a and earlier leaks translated IP addresses in ICMP error messages. | ||
| CVE-2019-11360 | Med | 0.00 | 4.2 | 0.02 | Jul 12, 2019 | A buffer overflow in iptables-restore in netfilter iptables 1.8.2 allows an attacker to (at least) crash the program or potentially gain code execution via a specially crafted iptables-save file. This is related to add_param_to_argv in xshared.c. | ||
| CVE-2015-6496 | 0.00 | — | 0.03 | Aug 24, 2015 | conntrackd in conntrack-tools 1.4.2 and earlier does not ensure that the optional kernel modules are loaded before using them, which allows remote attackers to cause a denial of service (crash) via a (1) DCCP, (2) SCTP, or (3) ICMPv6 packet. | |||
| CVE-2012-2663 | 0.00 | — | 0.03 | Feb 15, 2014 | extensions/libxt_tcp.c in iptables through 1.4.21 does not match TCP SYN+FIN packets in --syn rules, which might allow remote attackers to bypass intended firewall restrictions via crafted packets. NOTE: the CVE-2012-6638 fix makes this issue less relevant. | |||
| CVE-2003-0187 | 0.00 | — | 0.02 | Aug 27, 2003 | 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,… | |||
| CVE-2001-1388 | 0.00 | — | 0.01 | Nov 5, 2001 | iptables before 1.2.4 does not accurately convert rate limits that are specified on the command line, which could allow attackers or users to generate more or less traffic than intended by the administrator. | |||
| CVE-2001-1387 | 0.00 | — | 0.00 | Nov 5, 2001 | iptables-save in iptables before 1.2.4 records the "--reject-with icmp-host-prohibited" rule as "--reject-with tcp-reset," which causes iptables to generate different responses than specified by the administrator, possibly leading to an information leak. |
