CVE-2020-13757
Python-RSA decryption of ciphertext leads to DoS
7.5
HIGH
CVSS 3.1
EPSS 1.4%
描述
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).
