Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Information Disclosure: The use of uninitialized memory allocation APIs during DNS packet creation allowed remote attackers to read raw heap memory from the Node.js process space via malformed queries. This was a critical flaw disclosed under CVE-2021-23386.

Information Disclosure: Legacy Node.js Buffer constructors were utilized without strict input sanitization or safe-buffer wrappers, exposing the system to memory disclosure when non-string inputs were processed.
