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.

HighCVSS 7.5 EPSS 1.9%
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.
