| CVE | 摘要 | 来源 | 最高 CVSS | EPSS % | 公开时间 | 更新时间 |
|---|---|---|---|---|---|---|
| CVE-2019-11360 | 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. | [email protected] | 4.2 | 1.81% | 2019-07-12 | 2024-11-21 |
| CVE-2015-6496 | 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. | [email protected] | 5.0 | 3.20% | 2015-08-24 | 2026-05-06 |
| CVE-2012-2663 | 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. | [email protected] | 7.5 | 2.85% | 2014-02-15 | 2026-04-29 |
| CVE-2001-1388 | 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. | [email protected] | 5.0 | 1.07% | 2001-11-05 | 2026-04-16 |
| CVE-2001-1387 | 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. | [email protected] | 2.1 | 0.40% | 2001-11-05 | 2026-04-16 |
