  "details" : [ "pypdf is a free and open-source pure-python PDF library. Prior to 6.7.1, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires accessing the children of a TreeObject, for example as part of outlines. This vulnerability is fixed in 6.7.1.", "A flaw was found in pypdf. An attacker can craft a malicious PDF file that, when processed, leads to an infinite loop. This occurs when accessing specific elements within the PDF structure, such as the children of a TreeObject, which can be part of outlines. This vulnerability results in a Denial of Service (DoS), making the application unresponsive." ],
