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.

It was discovered that there was an issue in the Go programming language library where an attacker could generate a MIME request such that the server ran out of file descriptors.

For Debian 7 'Wheezy', this issue has been fixed in golang version 2:1.0.2-1.1+deb7u1.

We recommend that you upgrade your golang packages.
