 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4049-1 [email protected] https://www.debian.org/lts/security/ Andrej Shadura February 11, 2025 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : rust-openssl Version : 0.10.29-1+deb11u1 CVE ID : CVE-2025-24898

 A vulnerability has been discovered in rust-openssl, 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. This security update fixes the signature of ssl::select_next_proto to properly constrain the output buffer's lifetime to that of both input buffers. 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.

 For Debian 11 bullseye, this problem has been fixed in version 0.10.29-1+deb11u1.

 We recommend that you upgrade your rust-openssl packages.
