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).

Affected: Ubuntu:Pro:14.04:LTS: python-rsa

It was discovered that Python-RSA incorrectly handled certain ciphertexts. An attacker could possibly use this issue to obtain sensitive information.
