Amazon Linux 2 Security Advisory: ALAS-2020-1470
Advisory Release Date: 2020-07-31 19:21 Pacific
Advisory Updated Date: 2020-08-05 06:35 Pacific
Severity:
Medium
Issue Overview:
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)
Affected Packages:
python-rsa
Note:
This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.
Issue Correction:
Run yum update python-rsa to update your system.
