Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
MOOS core-moos through 10.4.0 contains a buffer overflow vulnerability in CMOOSSerialPort::GetTelegram() that writes a NUL terminator one byte past the serial telegram stack buffer. Attackers controlling the serial line can send a full-length telegram to trigger the off-by-one write, corrupting the stack and potentially enabling code execution.
