CVE-2020-28367

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.

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.

The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code.

This can be caused by malicious gcc flags specified via a cgo directive.

An input validation vulnerability was found in go. From a generated go file (from the cgo tool) it is possible to modify symbols within that object file and specify code instead. An attacker could potentially use this flaw by creating a repository which included malicious pre-built object files that could execute arbitrary code when downloaded and run via "go get" or "go build" whilst building a go project (CVE-2020-28366).

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. An attacker could potentially use this flaw by creating a malicious repository which would execute arbitrary code when downloaded and run via "go get" or "go build" whilst building a go project (CVE-2020-28367).
