FKIE_CVE-2025-24898
Vulnerability from fkie_nvd - Published: 2025-02-03 18:15 - Updated: 2026-06-17 08:59
Severity
Summary
rust-openssl is a set of OpenSSL bindings for the Rust programming language. In affected versions `ssl::select_next_proto` can return a slice pointing into the `server` argument's buffer but with a lifetime bound to the `client` argument. In situations where the `sever` buffer's lifetime is shorter than the `client` buffer's, this can cause a use after free. This could cause the server to crash or to return arbitrary memory contents to the client. The crate`openssl` version 0.10.70 fixes the signature of `ssl::select_next_proto` to properly constrain the output buffer's lifetime to that of both input buffers. Users are advised to upgrade. In standard usage of `ssl::select_next_proto` in the callback passed to `SslContextBuilder::set_alpn_select_callback`, code is only affected if the `server` buffer is constructed *within* the callback.

"value": "rust-openssl es un conjunto de enlaces OpenSSL para el lenguaje de programaci\u00f3n Rust. En las versiones afectadas, `ssl::select_next_proto` puede devolver un fragmento que apunta al b\u00fafer del argumento `server` pero con un tiempo de vida vinculado al argumento `client`. En situaciones en las que el tiempo de vida del b\u00fafer `sever` es m\u00e1s corto que el del `client`, esto puede provocar un use after free. Esto podr\u00eda provocar que el servidor se bloquee o que devuelva contenido de memoria arbitrario al cliente. La versi\u00f3n 0.10.70 del paquete `openssl` corrige la firma de `ssl::select_next_proto` para restringir adecuadamente el tiempo de vida del b\u00fafer de salida al de ambos b\u00faferes de entrada. Se recomienda a los usuarios que actualicen. En el uso est\u00e1ndar de `ssl::select_next_proto` en la devoluci\u00f3n de llamada pasada a `SslContextBuilder::set_alpn_select_callback`, el c\u00f3digo solo se ve afectado si el b\u00fafer `servidor` se construye *dentro* de la devoluci\u00f3n de llamada."
