pypdf has long runtimes for wrong size values in cross-reference and object streams
Impact
An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with wrong large /Size values or object streams with wrong large /N values.
Patches
This has been fixed in pypdf==6.10.1.
Workarounds
If you cannot upgrade yet, consider applying the changes from PR #3733.
