Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. Scored by CNA (rapid7.com).
Official description
An authenticated attacker may trigger a stack based buffer overflow by performing a malformed request to either the HTTP service (TCP port 80), the HTTPS service (TCP port 443), or the IPP service (TCP port 631). The malformed request will contain an empty Origin header value and a malformed Referer header value. The Referer header value will trigger a stack based buffer overflow when the host value in the Referer header is processed and is greater than 64 bytes in length.

The underlying weakness: Stack-based Buffer Overflow
The product writes past the end of a buffer that was allocated on the stack.
How developers prevent this class of flaw
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
- Use an abstraction library to abstract away risky APIs. Not a complete solution.
- Implement and perform bounds checking on input.
