| Doc Text: |
A flaw was found in pypdf, a free and open-source pure-python PDF library. A remote attacker could exploit this vulnerability by crafting a malicious PDF file. This file, containing specific cross-reference streams with `/W [0 0 0]` values and large `/Size` values, can lead to excessively long processing times. This can result in a Denial of Service (DoS) for applications processing such PDFs.
