We feel that this should not have a CVE ID because the removed curl and wget options had been intentional behavior. In other words, the vendor was not particularly interested in ensuring that the client was communicating with the correct web site. That required relying on third parties (maintainers of curl and wget) to maintain certificate data. Instead, the vendor was interested in whether the client was downloading the correct file. Achieving that can be independent. - -- CVE Assignment Team M/S M300, 202 Burlington Road, Bedford, MA 01730 USA [ A PGP key is available for encrypted communications at http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCAAGBQJXFwYcAAoJEHb/MwWLVhi2lS4P/3g0tuTBDJFhdPjGYs52WncH 4oyAXUPboTN/1ED1D9bcmARcBjE1lik2yMoM4JU0nuwiCj9aPwkXofpt8TCp3As8 haSrupzKzU0bpHeDVnTwXyc4a04CQ9WAaPDqDgPRViZN7AYKoyhF02zVxNN4jyXu CCPp3YsJCHLUvx5UFCFf5XevQBikINm1HuJiizoePHqrl5l6g0efsOulIpC4cGLo OobJanX3QNYNQe/bVfFS0R/tJysyDErSRLYzN3prhDDgoe/F1q1Unp/BKlEh0Cub +y0tw420qnIAhebz2CD3jgO5rAv1RA8zXOETtNl/m93oG/lyJa9YDRTXxetuW3K6 ulOQUrlM0l05cmsLKAYuqtPzeEyv6umfGhH/cG4NjHiaUlgXqihNdHRMjcQl5Bx8 XZ6cAn9XHuMqYBDffuSRspsXIkCZYzwlS6CRqy4uyPN+HH33CB5NHfRAhZFiEDY6 vK3cRgkcjrU6w6yQ43O8ttNiN6YpFocGXfImf/8FM1jcwBjsnl8IKufdZCKS+NJj 8/2Atu+aCdbhEVV+i3iEeeL806c1fH92JKmZxWvkU4/6W8xVS2uITqmuVRhg++5n tjTH4TrCpi1yjOsl3+PfSSqSsmoVrPe+hHRCXRZYmQ86b+eZXGr2oQt3Cic4xx21 FakLj9DAVjQBfk65+Jud =/IEH -----END PGP SIGNATURE-----
