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

Medium Nessus Plugin ID 139338

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

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.
