Impact
An attacker who uses this vulnerability can craft a PDF which leads to the RAM being exhausted. This requires accessing the
xfa property of a reader or writer and the corresponding stream being compressed using /FlateDecode.Patches
This has been fixed in pypdf==6.7.3.
Workarounds
If projects cannot upgrade yet, consider applying the changes from PR #3658.
