CVE-2021-44462

This vulnerability can be exploited by parsing maliciously crafted project files with Horner Automation Cscape EnvisionRV v4.50.3.1 and prior. The issues result from the lack of proper validation of user-supplied data, which can result in reads and writes past the end of allocated data structures. User interaction is required to exploit this vulnerability as an attacker must trick a valid user to open a malicious HMI project file.
