Descriptions

Code injection in the go command with cgo before Go 1.14.12 and Go 1.15.5 allows arbitrary code execution at build time via malicious gcc flags specified via a #cgo directive.

La inyección de código en el comando go con cgo antes de Go 1.14.12 y Go 1.15.5 permite la ejecución de código arbitrario en tiempo de compilación a través de banderas gcc maliciosas especificadas a través de una directiva #cgo

An input validation vulnerability was found in Go. If cgo is specified in a Go file, it is possible to bypass the validation of arguments to the gcc compiler. This flaw allows an attacker to create a malicious repository that can execute arbitrary code when downloaded and run via `go get` or `go build` while building a Go project. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability.
