    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"

    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).
