Prior to 6.21.3, pypdf can take excessive time to retrieve page labels from a crafted PDF containing a flat page-label number tree with many ranges. The page_labels property resolves each page independently and repeatedly scans the same /Nums array from the beginning, causing work to grow with both the page count and the number of label ranges. This issue is fixed in version 6.21.3.</p> <p><strong>Affected:</strong> py-pdf pypdf</p> <p>pypdf is a free and open-source pure-python PDF library.
