Vulnerability Data
A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation will surface code paths that detect errors yet perform no subsequent action.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Declaring incidents when criteria are met forces action on detected errors; eliminating the weakness helps but does not define the criteria themselves.
Triaging and validating reports compels follow-up on detections; removing the weakness supports but does not replace triage processes.
Analysis of detected events directly counters ignoring them, but does not guarantee every error condition is covered.
Monitoring produces detections, yet supplies no requirement to act on them.
Generating logs enables later action but does not enforce handling of each error condition.
Root-cause analysis of incidents requires acting on detected anomalies, though it applies after an incident is already declared.

Security testing can uncover missing error handling, but does not ensure the weakness is eliminated in production code.
Logging captures error conditions but does not guarantee subsequent handling or remediation.
Monitoring activities can detect errors, yet without defined response procedures the weakness persists.
Secure development lifecycle practices encourage proper error handling, but do not mandate it for every detected condition.
Secure coding standards typically require explicit error handling, reducing the likelihood of silent failures.
