Found in HEAD commit: 95eb6599dc4df30dfdb35380e8ecca4549ae0381

Found in base branch: main

Vulnerability Details

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation).
