--- Comment #3 from Johannes Ullrich <jullrich@xxxxxxxx> 2012-03-09 22:38:12 PST ---
RFC 5722 refers to fragments. This bug affects TCP segments. For TCP segments,
the first segment *should* be used if two segments with identical sequence
number are sent. However, in this case, the first segment uses an invalid
hop-by-hop header. As a result, the first segment will not be used. See the
ICMP parameter problem message that is sent as a result. Wireshark re-assembles
the traffic wrong. It should not consider the first segment with the bad
hop-by-hop header.

(Also changed platform/OS to "all" as this bug appears to be not platform
specific)
