## Affected

- NI IO Trace Tool: through 24.3

## Description

A stack-based buffer overflow vulnerability due to a missing bounds check in the NI I/O Trace Tool may result in arbitrary code execution. Successful exploitation requires an attacker to provide a user with a specially crafted nitrace file. The NI I/O Trace tool is installed as part of the NI System Configuration utilities included with many NI software products. Refer to the NI Security Advisory for identifying the version of NI IO Trace.exe installed. The NI I/O Trace tool was also previously released as NI Spy.
