Description Zack Miele 2022-08-08 13:30:57 UTC

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.

 In case you can't make full version update at the moment, bug tracker
ticket has also a patch for this single issue attached:

Please note the CVE used here is not correct and was caused probably by a mentioning in the Debian bug for freeciv, which later on got corrected. The CVE assigned by MITRE for this freeciv issue is CVE-2022-39047.
