DESCRIPTION:
Debian has issued an update for elinks. This fixes a weakness, which
can be exploited by malicious people to conduct spoofing attacks.

The weakness is caused due to the HTTP Negotiate or GSS-Negotiate
feature unconditionally performing credential delegation, which
allows a server to obtain the client's security credentials. This can
be exploited by a malicious server to impersonate the client to any
other server using the same GSSAPI mechanism.

Successful exploitation requires tricking a user into connecting to a
malicious server using the HTTP Negotiate or GSS-Negotiate feature.

SOLUTION:
Apply updated packages via the apt-get package manager.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Marko Myllynen within a bug report.
