Found by oss-fuzz
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=24288

Reproducer is
./src/suricata -r fail.pcap -S ip4hdr.rule
with ip4hdr.rule being a rule using ipv4.hdr alert ip any any -> any any (ipv4.hdr; content:"|00 00|"; offset:4; depth:2; sid:1234;)

The bug seems to be present for tcphdr as well
