EulerOS Virtualization 2.9.0 : python3 (EulerOS-SA-2023-1229)

high Nessus Plugin ID 169765

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the python3 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int('text'), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)

 - Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states 'Warning: http.server is not recommended for production. It only implements basic security checks.' (CVE-2021-28861)

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 python3 packages.
