CVE-2012-2663 [HIGH] CVE-2012-2663: extensions/libxt_tcp.c in iptables through 1.4.21 does not match TCP SYN+FIN packets in --syn rules, 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-2004-0986 [HIGH] CVE-2004-0986: Iptables before 1 Iptables before 1.2.11, under certain conditions, does not properly load the required modules at system startup, which causes the firewall rules to fail to load and protect the system from remote attackers.

CVE-2001-1388 [MEDIUM] CWE-770 CVE-2001-1388: iptables before 1.2.4 does not accurately convert rate limits that are specified on the command line 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 [LOW] CWE-203 CVE-2001-1387: iptables-save in iptables before 1.2.4 records the "--reject-with icmp-host-prohibited" rule as "--r 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.
