Name of the Vulnerable Software and Affected Versions DASH 7 Alliance protocol versions prior to 0.5.0

Description The Sub-IoT implementation of the DASH 7 Alliance protocol has a vulnerability that can lead to an out-of-bounds write. If the protocol has been compiled using default settings, this will only grant the attacker access to allocated but unused memory. However, if it was configured using non-default settings, there is the possibility that exploiting this vulnerability could lead to system crashes and remote code execution.

Recommendations For versions prior to 0.5.0, update to version 0.5.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the protocol until a patch is available. Avoid using non-default settings for the protocol configuration to minimize the risk of exploitation.
