Heap Buffer Overflows in YAML Parser: How Unchecked memcpy Calls Create Critical Attack Vectors

A critical heap buffer overflow vulnerability was discovered and patched in the YAML parser embedded within an Android VPN application, where five unvalidated `memcpy` calls could allow an attacker to corrupt heap memory by supplying a crafted YAML configuration file. This class of vulnerability is particularly dangerous because it can lead to arbitrary code execution or application crashes in security-sensitive contexts. The fix adds proper bounds validation before each copy operation, eliminat
