Hello gophers,

We have just released Go versions 1.23.5 and 1.22.11, minor point
releases.

These minor releases include 2 security fixes following the security
policy:

    crypto/x509: usage of IPv6 zone IDs can bypass URI name
constraints

    A certificate with a URI which has a IPv6 address with a zone ID
    may incorrectly satisfy a URI name constraint that applies to the
    certificate chain.

    Certificates containing URIs are not permitted in the web PKI,
    so this only affects users of private PKIs which make use of URIs.

    Thanks to Juho Forsén of Mattermost for reporting this issue.

    This is CVE-2024-45341 and Go issue https://go.dev/issue/71156.

    net/http: sensitive headers incorrectly sent after cross-domain
redirect

    The HTTP client drops sensitive headers after following a
cross-domain redirect.
    For example, a request to a.com/ containing an Authorization
    header which is redirected to b.com/ will not send that header
    to b.com.

    In the event that the client received a subsequent same-domain
    redirect, however, the sensitive headers would be restored. For
    example, a chain of redirects from a.com/, to b.com/1, and
    finally to b.com/2 would incorrectly send the Authorization
    header to b.com/2.

    Thanks to Kyle Seely for reporting this issue.

    This is CVE-2024-45336 and Go issue https://go.dev/issue/70530.

You can download binary and source distributions from the Go website:

To compile from source using a Git clone, update to the release with
git checkout go1.23.5 and build as usual.

Thanks to everyone who contributed to the releases.

Cheers,
Michael and Dmitri for the Go team
