For one, 5.6.1 was also released by "Jia Tan" according to: https://tukaani.org/xz-backdoor/ To fix bugs in the backdoor partly introduced in 5.6.0... e.g. not to remove the backdoor, but to make it a working backdoor. In other words, DO NOT USE 5.6.1. :) There are some concerns about questionable code by "Jia Tan" in earlier versions too: https://bugs.debian.org/1068024 ... although even the 5.4.x version I proposed was, admittedly, being a bit lazy and just picking a version already present in core-updates as the easiest path forward that was reasonably close to the version present in Debian which diffoscope was tested against... Reverting to 5.3.1 might be a more conservative approach, although I have not tested it with diffoscope. Or fixing diffoscope to work with the older xz version in master (5.2.x?) that guix is already using, which, now that I have spelled out all of the above, seems possibly a much better idea! live well, vagrant --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQRlgHNhO/zFx+LkXUXcUY/If5cWqgUCZkw40AAKCRDcUY/If5cW qo+dAP9ocBC+5ewzvFr/dqSFFWOb1KO6ufTSlhFWxfe7f2y+zQEA/xmN9hUGfAQH GNTzWIfW1PoA7Kq9ukPkqSSeXDoRpg0= =OMqX -----END PGP SIGNATURE----- --=-=-=--
