About this tag
The go runtime security tag on WindowsForum.com covers vulnerabilities and hardening topics specific to the Go runtime environment. Recent discussions focus on CVE-2023-29403, a privilege escalation flaw in Go's handling of setuid/setgid binaries. When privileged Go programs start with closed standard I/O file descriptors or crash, the runtime fails to sanitize the process environment, potentially allowing local attackers to read or write attacker-controlled files or leak register and memory state. The tag includes analysis of affected Go versions, exploitation scenarios, and mitigation strategies for developers and system administrators securing Go applications.
