Update to Go 1.19.3 to address CVE-2022-41716 - #3850
Merged
Conversation
On Windows, syscall.StartProcess and os/exec.Cmd did not properly check for invalid environment variable values. A malicious environment variable value could exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" set the variables "A=B" and "C=D". Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue. This is CVE-2022-41716 and Go issue https://go.dev/issue/56284. This Go release also fixesgolang/go#56309, a runtime bug which can cause random memory corruption when a goroutine exits with runtime.LockOSThread() set. This fix is necessary to unblock work to replace certain uses of pkg/reexec with unshared OS threads. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
