NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-src package and not the golang-src package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
