Overview

openssl-src is a crate that contains the logic to build OpenSSL and is intended to be consumed by the openssl-sys crate.

Affected versions of this package are vulnerable to Timing Attack in rsa/rsa_ossl.c. An attacker can recover ciphertext with a Bleichenbacher style attack by sending a large number of trial messages (Marvin). This affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP, and RSASVE.
