| Package | Affected versions | Patched versions |
|---|---|---|
| rsa | < 4.1 | 4.1 |
| python-rsa | < 4.1 | 4.1 |
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).
