SCA: security update for pypdf (GHSA-7hfw-26vp-jp8m)

high Tenable Cloud Security Plugin ID 433344

Description

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

 - pypdf is a free and open-source pure-python PDF library. Prior to version 6.0.0, an attacker can craft a
 PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode
 filters is used on a malicious cross-reference stream. Other content streams are affected on explicit
 access. This issue has been fixed in 6.0.0. If an update is not possible, a workaround involves including
 the fixed code from pypdf.filters.decompress into the existing filters file. (CVE-2025-55197)
