Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
This 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.
### Patches
Fixed as of version 2.6.7
### Workarounds
No.
