Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly counters the CWE-787 out-of-bounds write in gethostbyname by enforcing memory protections that block arbitrary code execution from malformed DNS responses.

prevent

Restricts local user privileges so that even successful exploitation of the DNS-handling flaw cannot yield full system code execution.

prevent

Requires validation and sanitization of all input, including DNS return data processed by gethostbyname, to prevent the malformed responses that trigger the overflow.

PR.PS-06 mostly match
prevents

Secure-development practices (static analysis, bounds checking, code review) are the primary means of preventing out-of-bounds writes.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

detects

Security testing in development and acceptance can detect and prevent out-of-bounds write defects.

prevents

Secure development life cycle mandates practices that prevent out-of-bounds writes.

prevents

Application security requirements can specify bounds-checking and safe memory handling.

prevents

Secure architecture and engineering principles reduce the likelihood of buffer overflows.

prevents

Secure coding directly addresses out-of-bounds writes through language choice and coding standards.

prevents

Change management can enforce review gates that catch unsafe memory operations before deployment.
