# ipphelper.c: stack buffer overflow from missing bounds check, remote crash

Multiple functions in ipphelper.c lack a bounds check, allowing a stack buffer overflow. A remote attacker can crash the affected component, causing denial of service, with no extra privileges and no user interaction.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

In multiple functions of ipphelper.c, there is a possible stack bugger overflow due to a missing bounds check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.
