Explanation

A Buffer Overflow (B) occurs when a program writes more data to a memory buffer than it can hold, causing adjacent memory to be overwritten. The symptoms here match exactly: the application crashes with a memory error, and the debug logs show code being executed via an internal process - classic signs that an attacker has overflowed a buffer to redirect execution flow to malicious shellcode. Zero-day refers to an unknown vulnerability, XSS is a web-based attack, and a malicious add-on is a different attack vector entirely.
