AlmaLinux 8 : python38:3.8 and python38-devel:3.8 (ALSA-2023:2763)
high Nessus Plugin ID 176153
Synopsis
The remote AlmaLinux host is missing one or more security updates.Description
The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:2763 advisory.- 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)
- ** DISPUTED ** 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)
- An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
