pypdf is a free and open-source pure-python PDF library. Prior to 6.12.0, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with /W [0 0 0] values and large /Size values. This vulnerability is fixed in 6.12.0.
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.
Отчет
This flaw has a Low impact. Red Hat products that process PDF files using the pypdf library are vulnerable to a denial of service. An attacker could provide a specially crafted PDF, causing applications to experience prolonged processing times and potential resource exhaustion. This risk is limited to scenarios where untrusted PDF content is handled.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
