Wesnoth developers mailing list mentions security fix currently being worked on upstream: https://mail.gna.org/public/wesnoth-dev/2009-02/msg00036.html Further details and upstream bug report are currently non-public: https://gna.org/bugs/index.php?13037
There's currently not much info about this at the moment, though I filed this bug to make maintainers aware of the other upcoming security fix besides CVE-2009-0367, so they can be done in one update if desired.
Debian Security Advisory DSA-1737-1 has just been released referring to this CVE: http://lists.debian.org/debian-security-announce/2009/msg00047.html http://www.debian.org/security/2009/dsa-1737 describing the flaw as: CVE-2009-0366 Daniel Franke discovered that the wesnoth server is prone to a denial of service attack when receiving special crafted compressed data. The patch they used is upstream SVN r33069 http://svn.gna.org/viewcvs/wesnoth?view=rev&rev=33069 Upstream bug report is still private, and I do not see any other public reference that would match r33069 to bug gna#13037 or CVE-2009-0366.
