Official description
A vulnerability exists in the IEC 61850 communication stack that affects multiple Hitachi Energy products. An attacker could exploit the vulnerability by using a specially crafted message sequence, to force the IEC 61850 MMS-server communication stack, to stop accepting new MMS-client connections. Already existing/established client-server connections are not affected.

The underlying weakness: Improper Resource Shutdown or Release
The product does not release or incorrectly releases a resource before it is made available for re-use.
How developers prevent this class of flaw
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
- It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free memory in a function. If you allocate memory that you intend to free upon completion of the function, you must be sure to free the memory at all exit points for that function including error conditions.
- Memory should be allocated/freed using matching functions such as malloc/free, new/delete, and new[]/delete[].
