M Loop with Unreachable Exit Condition ('Infinite Loop') pypdf is an A pure-python PDF library capable of splitting, merging, cropping, and transforming PDF files Affected versions of this package are vulnerable to Loop with Unreachable Exit Condition ('Infinite Loop') when the `PdfWriter(clone_from)` function is used with a PDF. An attacker can craft a PDF that 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. This is particularly problematic when the user manipulates an incoming malicious PDF, for example, by merging it with another PDF or by adding annotations. How to fix Loop with Unreachable Exit Condition ('Infinite Loop')? Upgrade `pypdf` to version 3.17.0 or higher.	[3.7.0,3.17.0)
