pypdf has inefficient decoding of array-based streams

pypdf is a free and open-source pure-python PDF library. Versions prior to 6.9.1 allow an attacker to craft a malicious PDF which leads to long runtimes and/or large memory usage. Exploitation requires accessing an array-based stream with many entries. This issue has been fixed in version 6.9.1.

pypdf has possible Infinite Loop when processing outlines/bookmarks

pypdf is a free and open-source pure-python PDF library.
