A flaw was found in pypdf, a pure-Python PDF library. A remote attacker can craft a malicious PDF document containing an unterminated inline image within its page content stream. When a user processes this crafted PDF, such as during text extraction, the vulnerability causes an infinite loop, leading to a Denial of Service (DoS) condition. This issue impacts the availability of the pypdf application.
