SCA: security update for PyPDF2 (GHSA-xcjx-m2pj-8g79)

medium Tenable Cloud Security Plugin ID 420436

Description

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

 - PyPDF2 is an open source python PDF library capable of splitting, merging, cropping, and transforming the
 pages of PDF files. In versions prior to 1.27.5 an attacker who uses this vulnerability can craft a PDF
 which leads to an infinite loop if the PyPDF2 if the code attempts to get the content stream. The reason
 is that the last while-loop in `ContentStream._readInlineImage` only terminates when it finds the `EI`
 token, but never actually checks if the stream has already ended. This issue has been resolved in version
 `1.27.5`. Users unable to upgrade should validate and PDFs prior to iterating over their content stream.
 (CVE-2022-24859)
