| Doc Text: |
A flaw was found in pypdf. This vulnerability allows an attacker to cause a Denial of Service (DoS) by tricking a user or application into processing a specially crafted PDF document. When the library parses an incomplete file where the cross-reference table ends without a trailer, the parser repeatedly rewinds to the same position instead of terminating. This behavior triggers an infinite loop, hanging the processing thread and rendering the application unresponsive.
