cmd/go: golang: Go (golang) and cmd/go: Arbitrary Code Execution via malicious SWIG file names

A flaw was found in the Go programming language golang and its command-line tool cmd/go. A remote attacker could exploit this during the build process by crafting malicious SWIG Simplified Wrapper and Interface Generator file names that contain "cgo" and specific payloads. This could lead to code...
