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...

GHSA-QPXP-75PX-XJCP pypdf has inefficient decoding of array-based streams

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes and/or large memory usage. This requires accessing an array-based stream with lots of entries. Patches This has been fixed in pypdf==6.9.1. Workarounds If you cannot upgrade yet, consider applying the...
