pypdf has possible long runtimes/large memory usage for encrypted PDF files
### Impact
An attacker who uses this vulnerability can craft a PDF which leads to large runtimes/memory usage. This requires accessing the page count of an encrypted PDF file, which itself declares a wrong `/Count` value.
### Patches
This has been fixed in [pypdf==6.21.3](https://github.com/py-pdf/pypdf/releases/tag/6.21.3).
### Workarounds
If you cannot upgrade yet, consider applying the changes from PR [#4270](https://github.com/py-pdf/pypdf/pull/4270).
