CVE-2024-52813

matrix-rust-sdk is an implementation of a Matrix client-server library in Rust. Versions of the matrix-sdk-crypto Rust crate before 0.8.0 lack a dedicated mechanism to notify that a user's cryptographic identity has changed from a verified to an unverified one, which could cause client applications relying on the SDK to overlook such changes. matrix-sdk-crypto 0.8.0 adds a new VerificationLevel::VerificationViolation enum variant which indicates that a previously verified identity has been changed.

matrix-rust-sdk es una implementación de una librería cliente-servidor Matrix en Rust. Las versiones del paquete de Rust matrix-sdk-crypto anteriores a la 0.8.0 carecen de un mecanismo dedicado para notificar que la identidad criptográfica de un usuario ha cambiado de verificada a no verificada, lo que podría provocar que las aplicaciones cliente que dependen del SDK pasen por alto dichos cambios. matrix-sdk-crypto 0.8.0 agrega una nueva variante de enumeración VerificationLevel::VerificationViolation que indica que se ha cambiado una identidad verificada previamente.
