Medium: python-rsa

Issue Overview:

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). (CVE-2020-13757)

Affected Packages:
