Описание
pypdf is a free and open-source pure-python PDF library. Prior to 6.14.2, an attacker can craft a PDF with a page content stream containing a not terminated inline image that uses the ASCII85 or ASCIIHex filters, causing an infinite loop during parsing such as when extracting page text. This issue is fixed in version 6.14.2.
A flaw was found in pypdf, a pure-python PDF library. A remote attacker can craft a malicious PDF file containing an unterminated inline image within the page content stream. When this crafted PDF is parsed, it can lead to an infinite loop, resulting in a denial of service (DoS) due to resource exhaustion.
Отчет
This Moderate flaw in the pypdf library allows a remote attacker to trigger a denial of service by providing a specially crafted PDF file. The vulnerability arises from an infinite loop during parsing of an unterminated inline image, which can exhaust system resources. While requiring user interaction to process a malicious PDF, the issue can lead to service unavailability in applications utilizing pypdf for PDF processing.
