Not Vulnerable:

NetBSD IPComp Implementation Stack Overflow Remote Memory Corruption Vulnerability

NetBSD is prone to a remote memory-corruption vulnerability because it fails to adequately check for stack overflows in nested IP Payload Compression protocol (IPComp) payloads.

Attackers can exploit this issue to trigger a kernel stack overflow, resulting in the execution of arbitrary code with superuser privileges. Failed attacks may cause a denial-of-service condition. A successful exploit will completely compromise affected computers.

This issue may affect systems derived from NetBSD IPComp implementations.
