Test ID:1.3.6.1.4.1.25623.1.1.10.2020.0364
Category:Mageia Linux Local Security Checks
Title:Mageia: Security Advisory (MGASA-2020-0364)
Summary:The remote host is missing an update for the 'python-rsa' package(s) announced via the MGASA-2020-0364 advisory.
Description:Summary:
The remote host is missing an update for the 'python-rsa' package(s) announced via the MGASA-2020-0364 advisory.

Vulnerability Insight:
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 Software/OS:
'python-rsa' package(s) on Mageia 7.

Solution:
Please install the updated package(s).

CVSS Score:
5.0

CVSS Vector:
