| Doc Text: |
A flaw was found in pypdf. A remote attacker could exploit this vulnerability by submitting a specially crafted PDF document containing unusually large tokens in font mapping streams. When the library parses this data during operations such as text extraction, it decodes and retains oversized values, leading to excessive memory consumption and a Denial of Service (DoS).
