"details": "### Impact\nThis is a significant Denial of Service (DoS) vulnerability. Any application that uses FPDI to process user-supplied PDF files is at risk. An attacker can upload a small, malicious PDF file that will cause the server-side script to crash due to memory exhaustion or a script time-out. Repeated attacks can lead to sustained service unavailability.\n\n### Patches\nFixed as of version 2.6.7\n\n### Workarounds\nNo.\n\n### References\nNo.",
