Just released freeciv-2.6.7 & freeciv-3.0.3 fix buffer overflow in
Modpack Installer utility's handling of the modpack URL. Specially
crafted URLs, without any '/' -characters would result in an
underflowing length (unsigned)(-1) string copy, i.e., all of the
NULL-terminated string given as "URL" would get written beyond the
buffer reserved for it.
Freeciv source tarballs are available from
https://www.freeciv.org/download.html for current 3.0, and from
https://www.freeciv.org/wiki/Old_downloads for 2.6.
