Package: hping3
Version: 3.a2.ds2-4
Severity: normal
Tags: patch
Hi,
it seems hping3, when working in udp mode, checks the size passed to
--data option with the size of a tcp header.
The attached patch should fix the problem using UDPHDR_SIZE when udp
mode is set, otherwise using TCPHDR_SIZE.
Please can you forward this patch upstream? Many parts of their website
seem down so I was not able to checkout latest sources and send a proper
patch to them.
Thank you,
Luca
