CVE-2012-2663 unimportant priority: Debian including 1 source packages (iptables), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
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.
