Hi Balint

No a problem for me to add PIE on Wireshark
But no need to check if lib (Qt) use also PIE ?
We already do--at least with autofoo (cmake seems to pick up the PIE flags from Qt's config directly).
But I don't think there's a problem if we're compiled PIE and libraries we use aren't.

    Hi All,

    I have just created a review to add PIE when it is available to
    default flags:
    https://code.wireshark.org/review/#/c/10635

    I think this matter is worth discussion here, too.
    Should we enable more compiler flags which make Wireshark more secure
    by default?

    I Debian I will enable all hardening flags thus Debian users will be
    protected, but I wonder if we want to enable some of them in vanilla
    Wireshark as well.
I don't have much of an opinion either way but Fedora also compiles Wireshark with PIE:
