DESCRIPTION:
A weakness has been reported in cURL, which can be exploited by
malicious people to conduct spoofing attacks.

The weakness is caused due to the 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 GSS/Negotiate feature.

The weakness is reported in versions 7.10.6 through 7.21.6.

SOLUTION:
Update to version 7.21.7 or apply patch.
