CVE-2025-61731
Arbitrary file write using cgo pkg-config directive in cmd/go
Overview
Description
Building a malicious file with cmd/go can cause can cause a write to an attacker-controlled file with partial control of the file content. The "#cgo pkg-config:" directive in a Go source file provides command-line arguments to provide to the Go pkg-config command. An attacker can provide a "--log-file" argument to this directive, causing pkg-config to write to an attacker-controlled location.

Solution
Sanitize input for pkg-config directives to prevent arbitrary file writes.
- Validate input used in '#cgo pkg-config:' directives.
- Remove or sanitize '--log-file' arguments.
- Avoid using untrusted input in build directives.
- Update build tools and dependencies.
