Critical Heap Buffer Overflow Fixed in GeoIP Database Parser

A critical heap buffer overflow vulnerability was discovered and patched in a GeoIP database parser, where raw `memcpy` operations were performed without proper bounds validation across three separate code locations. An attacker who could supply a malicious GeoIP database file could potentially achieve arbitrary code execution or crash the application. The fix introduces strict bounds checking before every memory copy operation, eliminating the attack surface entirely.
