Kerentanan Use of a Broken or Risky Cryptographic Algorithm pada python-rsa project python-rsa, fedoraproject fedora +1 lainnya. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

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).
