In AutomationDirect C-MORE EA9 HMI there is a program that copies a buffer of a size controlled by the user into a limited sized buffer on the stack which may lead to a stack overflow. The result of this stack-based buffer overflow can lead to denial-of-service conditions.
Solution:
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
