Fedora has issued an advisory for this today (February 14):
https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/FUXKJDF62YGEI7SVFFUYQ56QCKESXF3W/

Hopefully we can find a patch for this so we don't have to get back on the development release train.

Comment 6 Nicolas Salguero 2017-02-17 11:31:17 CET

Suggested advisory:
========================

The updated package fix a security vulnerability:

Lynx doesn't parse the authority component of the URL correctly when the host name part ends with '?', and could instead be tricked into connecting to a different host. (CVE-2016-9179)

32-bit version

Installed lynx and was able to browse around the Mageia website.  Seems to work from a base perspective

Trying http://www.google.ca?localhost both before and after the update fails, so
not sure how to recreate the bug.

Normal web browsing is working, so validating the update.
