Amazon Linux 2 : python-rsa (ALAS-2020-1470)

high Nessus Plugin ID 139338

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

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).
(CVE-2020-13757)

Solution

Run 'yum update python-rsa' to update your system.
