Описание
pypdf is a free and open-source pure-python PDF library. Prior to version 6.6.0, pypdf has possible long runtimes for missing /Root object with large /Size values. An attacker who uses this vulnerability can craft a PDF which leads to possibly long runtimes for actually invalid files. This can be achieved by omitting the /Root entry in the trailer, while using a rather large /Size value. Only the non-strict reading mode is affected. This issue has been patched in version 6.6.0.
A flaw was found in pypdf. A remote attacker can exploit this vulnerability by crafting a malicious PDF file that omits the /Root entry in the trailer and uses a large /Size value. This can lead to excessively long processing times when the PDF is read in non-strict mode, resulting in a Denial of Service (DoS) for the affected system.
Отчет
This vulnerability is rated Moderate. The pypdf library, when processing a specially crafted PDF file that omits the /Root entry and uses a large /Size value in non-strict mode, can lead to excessively long processing times, resulting in a Denial of Service. This affects various components within Red Hat Ansible Automation Platform, OpenShift Lightspeed, Red Hat Enterprise Linux AI, Red Hat OpenShift AI, and Ansible Services.
