The digest generation function of NHIServiSignAdapter has not been verified for parameter’s length, which leads to a stack overflow loophole. Remote attackers can use the leak to execute code without privilege.
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).
The product writes data past the end, or before the beginning, of the intended buffer.
