EulerOS 2.0 SP5 : python-rsa (EulerOS-SA-2020-2267)

high Nessus Plugin ID 142111

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the python-rsa package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-rsa package.
