Описание
pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.2 can craft a PDF which leads to the RAM being exhausted. This requires accessing an image using /FlateDecode with large size values. This has been fixed in pypdf 6.10.2. As a workaround, one may apply the changes from the patch manually.
A flaw was found in pypdf, a pure-Python PDF library. An attacker can exploit this vulnerability by crafting a malicious PDF file that accesses an image using /FlateDecode with large size values. This can lead to memory exhaustion, resulting in a Denial of Service (DoS) for the system processing the PDF.
Меры по смягчению последствий
To mitigate this issue, avoid processing untrusted PDF files with applications utilizing the pypdf library. Restricting the sources of PDF files to trusted origins can reduce the risk of exploitation.
