CVE-2020-13757
HIGH7.5EPSS 0.10%Python-RSA decryption of ciphertext leads to DoS
發布日:2021/3/24修改日:2024/10/21
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).
