Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-08-05 17:30:19 UTC
oss-security post:

"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."

Please bump to 3.0.3.
