Hello gophers,
We have just released Go versions 1.24.5 and 1.23.11, minor point releases.
These minor releases include 1 security fixes following the security policy:
cmd/go: unexpected command execution in untrusted VCS repositories
Various uses of the Go toolchain in untrusted VCS repositories can result in
unexpected code execution. When using the Go toolchain in directories
fetched
using various VCS tools (such as directly cloning Git or Mercurial
repositories)
can cause the toolchain to execute unexpected commands, if said directory
contains multiple VCS configuration metadata (such as a '.hg' directory in
a Git
repository). This is due to how the Go toolchain attempts to resolve which
VCS
is being used in order to embed build information in binaries and determine
module versions.
The toolchain will now abort attempting to resolve which VCS is being used
if it
detects multiple VCS configuration metadata in a module directory or nested
VCS
configuration metadata (such as a '.git' directoy in a parent directory and
a
'.hg' directory in a child directory). This will not prevent the toolchain
from
building modules, but will result in binaries omitting VCS related build
information.
If this behavior is expected by the user, the old behavior can be
re-enabled by
setting GODEBUG=allowmultiplevcs=1. This should only be done in trusted
repositories.
Thanks to RyotaK (https://ryotak.net) of GMO Flatt Security Inc for
reporting
this issue.
This is CVE-2025-4674 and https://go.dev/issue/74380.
View the release notes for more information:
https://go.dev/doc/devel/release#go1.24.5
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 go1.24.5 and build as usual.
Thanks to everyone who contributed to the releases.
Cheers,
Carlos and David for the Go team
