Описание

pypdf is a free and open-source pure-python PDF library. Prior to 6.16.0, an attacker can craft a PDF whose cyclic tree structure causes pypdf/generic/_data_structures.py TreeObject.insert_child to follow /Next links indefinitely when a writing code path inserts a child, producing an infinite loop. This issue is fixed in version 6.16.0.

A flaw was found in pypdf. An attacker can craft a malicious PDF document with a cyclic tree structure. When a writing code path attempts to insert a child object, the TreeObject.insert_child function can follow /Next links indefinitely, leading to an infinite loop. This can result in a denial of service (DoS) due to resource exhaustion.
