CWE-786
Access of Memory Location Before Start of Buffer
BaseIncomplete
Description
The product reads or writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.
This typically occurs when a pointer or its index is decremented to a position before the buffer, when pointer arithmetic results in a position before the beginning of the valid memory location, or when a negative index is used.
