CVE-2020-13757 (GCVE-0-2020-13757)

Vulnerability from cvelistv5 – Published: 2020-06-01 18:17 – Updated: 2024-08-04 12:25
VLAI
Summary
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).
Severity
No CVSS data available.
