Description

This security bulletin contains information about 2 secuirty vulnerabilities.

1) Improper Certificate Validation (CVE-ID: CVE-2017-1000097)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

On Darwin, user's trust preferences for root certificates were not honored. If the user had a root certificate loaded in their Keychain that was explicitly not trusted, a Go program would still verify a connection using that root certificate.

2) Input validation error (CVE-ID: CVE-2017-1000098)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

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.
