Overview

Allocated memory of zero size is used. This may lead to incorrect behavior or crash of the application.

The application uses malloc function, which allocates a block of memory with the specified argument size and returns a pointer to the beginning of a block. If the size is equal to zero, it is possible undefined behavior of the application.
