Doc Text:
A flaw was found in Go's 'cgo tool'. This vulnerability arises from a discrepancy in how Go and C/C++ comments are parsed, which allows for malicious code to be hidden within comments and then "smuggled" into the compiled `cgo` binary. An attacker could exploit this to embed and execute arbitrary code, potentially leading to significant system compromise.
