Improper bounds validation in the ZAP command parser of EmberZNet SDK versions 8.0.0 through 9.1.1 (inclusive) and before 7.5.2 (exclusive) may result in crashes or dynamic memory leakage. In order to exploit this vulnerability, an attacker would have to have the ability to send arbitrary messages on the network. The only known exploit of this vulnerability leaks a limited number of bytes from the stack. No denial-of-service, memory corruption, or remote code execution has been shown.
