How to fix?

Upgrade Debian:14 rust-openssl to version 0.10.78-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-openssl package and not the rust-openssl package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.39 to before 0.10.78, EVP_DigestFinal() always writes EVP_MD_CTX_size(ctx) to the out buffer. If out is smaller than that, MdCtxRef::digest_final() writes past its end, usually corrupting the stack. This is reachable from safe Rust. This vulnerability is fixed in 0.10.78.
