From the security mailing list:

> Hello gophers,
>
> We have just released Go versions 1.25.7 and 1.24.13, minor point releases.
>
> These releases include 2 security fixes following the security policy:
>
> - cmd/cgo: remove user-content from doc strings in cgo ASTs
>
>   A discrepancy between how Go and C/C++ comments
>   were parsed allowed for code smuggling into the
>   resulting cgo binary.
>
>   To prevent this behavior, the cgo compiler
>   will no longer parse user-provided doc
>   comments.
>
>   Thank you to RyotaK (https://ryotak.net) of
>   GMO Flatt Security Inc. for reporting this issue.
>
>   This is CVE-2025-61732 and https://go.dev/issue/76697.
>
> - crypto/tls: unexpected session resumption when using Config.GetConfigForClient
>
>   Config.GetConfigForClient is documented to use the original Config's session
>   ticket keys unless explicitly overridden. This can cause unexpected behavior if
>   the returned Config modifies authentication parameters, like ClientCAs: a
>   connection initially established with the parent (or a sibling) Config can be
>   resumed, bypassing the modified authentication requirements.
>
>   If ClientAuth is VerifyClientCertIfGiven or RequireAndVerifyClientCert (on the
>   server) or InsecureSkipVerify is false (on the client), crypto/tls now checks
>   that the root of the previously-verified chain is still in ClientCAs/RootCAs
>   when resuming a connection.
>
>   Go 1.26 Release Candidate 2, Go 1.25.6, and Go 1.24.12 had fixed a similar issue
>   related to session ticket keys being implicitly shared by Config.Clone. Since
>   this fix is broader, the Config.Clone behavior change has been reverted.
>
>   Note that VerifyPeerCertificate still behaves as documented: it does not apply
>   to resumed connections. Applications that use Config.GetConfigForClient or
>   Config.Clone and do not wish to blindly resume connections established with the
>   original Config must use VerifyConnection instead (or SetSessionTicketKeys or
>   SessionTicketsDisabled).
>
>   Thanks to Coia Prant (github.com/rbqvq) for reporting this issue.
>
>   This updates CVE-2025-68121 and Go issue https://go.dev/issue/77217.
