Denial Of Service

pypdf is vulnerable to Denial of Service. The vulnerability is due to inefficient decoding of array-based streams, where accessing an array-based stream with many entries leads to long runtimes and large memory usage, and attackers can exploit it by crafting a malicious PDF with a large array-bas...
