CVE-2024-3296

A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover a plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.

To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.

Existe un canal lateral basado en temporización en el paquete rust-openssl, que podría ser suficiente para recuperar un texto plano a través de una red en un ataque estilo Bleichenbacher. Para lograr un descifrado exitoso, un atacante tendría que poder enviar una gran cantidad de mensajes de prueba para descifrarlos. La vulnerabilidad afecta al modo de relleno de cifrado RSA PKCS#1v1.5 heredado.
