rh#1401985

The net/http package's Request.ParseMultipartForm method starts writing to
temporary files once the request body size surpasses the given "maxMemory"
limit. It was possible for an attacker to generate a multipart request crafted
such that the server ran out of file descriptors.

Comment 1 Jordi Massaguer 2018-03-07 13:59:28 UTC

This fix is in go1.8, go1.9, go1.10 and in go1.7 >= 1.7.5

All our packages should have this fix already.

Comment 2 Jordi Massaguer 2018-03-07 14:10:40 UTC

Also in go1.6 >= 1.6.4. All our instances of go1.6 already contain this version.
