Hello gophers, We have just released Go versions 1.20.5 and 1.19.10, minor point releases.
These minor releases include 3 security fixes following the security policy <https://go.dev/security>: - cmd/go: cgo code injection The go command may generate unexpected code at build time when using cgo. This may result in unexpected behavior when running a go program which uses cgo. This may occur when running an untrusted module which contains directories with newline characters in their names. Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected). Thanks to Juho Nurminen of Mattermost for reporting this issue. This is CVE-2023-29402 and Go issue https://go.dev/issue/60167. - runtime: unexpected behavior of setuid/setgid binaries The Go runtime didn't act any differently when a binary had the setuid/setgid bit set. On Unix platforms, if a setuid/setgid binary was executed with standard I/O file descriptors closed, opening any files could result in unexpected content being read/written with elevated prilieges. Similarly if a setuid/setgid program was terminated, either via panic or signal, it could leak the contents of its registers. Thanks to Vincent Dehors from Synacktiv for reporting this issue. This is CVE-2023-29403 and Go issue https://go.dev/issue/60272. - cmd/go: improper sanitization of LDFLAGS The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "#cgo LDFLAGS" directive. Thanks to Juho Nurminen of Mattermost for reporting this issue. This is CVE-2023-29404 and CVE-2023-29405 and Go issues https://go.dev/issue/60305 and https://go.dev/issue/60306. View the release notes for more information: https://go.dev/doc/devel/release#go1.20.5 You can download binary and source distributions from the Go website: https://go.dev/dl/ To compile from source using a Git clone, update to the release with git checkout go1.20.5 and build as usual. Thanks to everyone who contributed to the releases. Cheers, David and Michael for the Go team -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
