## Technical details

An out-of-bounds read vulnerability (CWE-125) exists in MZ Automation lib60870 versions 2.4.0 and prior. The flaw occurs during the parsing of network traffic, where the library may attempt to read data beyond the allocated buffer. A remote, unauthenticated attacker can exploit this by sending specially crafted packets to a system using the library. Successful exploitation results in a process crash (Denial of Service) and potentially limited information disclosure. The vendor has released version 2.4.1 to address this issue.

## Affected products
