AlmaLinux 9 : python3.9 (ALSA-2022:8353)

high Nessus Plugin ID 167866

Synopsis

The remote AlmaLinux host is missing one or more security updates.

Description

The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:8353 advisory.

 - In Python (aka CPython) through 3.10.4, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). (CVE-2015-20107)

 - ** 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
