NVD Description

Note: Versions mentioned in the description apply only to the upstream iptables package and not the iptables package as distributed by Ubuntu.

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.
