SCA: security update for PyPDF2 (GHSA-hm9v-vj3r-r55m)

medium Tenable Cloud Security Plugin ID 415835

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - pypdf is a pure-python PDF library capable of splitting, merging, cropping, and transforming the pages of
 PDF files. In version 2.10.5 an attacker who uses this vulnerability can craft a PDF which leads to an
 infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by
 100%. It does not affect memory usage. That is, for example, the case if the user extracted metadata from
 such a malformed PDF. Versions prior to 2.10.5 throw an error, but do not hang forever. This issue was
 fixed with https://github.com/py-pdf/pypdf/pull/1331 which has been included in release 2.10.6. Users are
 advised to upgrade. Users unable to upgrade should modify
 `PyPDF2/generic/_data_structures.py::read_object` to an an error throwing case. See GHSA-hm9v-vj3r-r55m
 for details. (CVE-2023-36807)
