Vulnerability Data

A vulnerability exists in the proxy packet processing logic of the affected component where it improperly processes malformed or truncated input. An unauthenticated remote attacker could exploit this vulnerability by providing specially crafted input that triggers an integer overflow. Successful…

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.

Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

finds

Security testing in development can detect integer overflows before release.

prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
