Show the technical text from the sources
SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device can send messages that cause the master to read data from memory locations beyond the intended buffer. The software uses length values from device responses without validating them against actual buffer sizes. An attacker can exploit this to extract up to 64KB of data from the master's memory.
