Pypdf 3.17.0 includes a fix for CVE-2023-46250: An attacker who uses a vulnerability present in versions 3.7.0 through 3.16.4 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 when the pypdf-user manipulates an incoming malicious PDF e.g. by merging it with another PDF or by adding annotations. As a workaround, apply the patch manually by modifying 'pypdf/generic/_data_structures.py'.
