Buffer overflow in (1) mrinfo, (2) mtrace, and (3) pppd in NetBSD 1.4.x through 1.6 allows local users to gain privileges by executing the programs after filling the file descriptor tables, which produces file descriptors larger than FD_SETSIZE, which are not checked by FD_SET().

Security readout for executives and security teams

Plain-English summary

CVE-2002-1500 is an old NetBSD local privilege-escalation issue. A logged-in local user could abuse vulnerable mrinfo, mtrace, or pppd behavior to gain higher privileges. It matters mainly for organizations still operating legacy NetBSD 1.4.x through 1.6 systems.

Executive priority

Prioritize if legacy NetBSD systems remain in production, especially shared or multi-user hosts. If no such systems exist, business urgency is low. The main risk is local users becoming privileged administrators.

Technical view

The CVE describes buffer overflows in NetBSD mrinfo, mtrace, and pppd. By filling file descriptor tables, a local user can cause file descriptors larger than FD_SETSIZE. These are not checked before FD_SET() use, enabling privilege gain when the programs execute.

Likely exposure

Exposure is limited to NetBSD 1.4.x through 1.6 systems where local users can execute the affected programs. The source does not indicate remote exploitation or affected non-NetBSD products.

Exploitation context

The issue requires local user access. The provided sources do not show active exploitation, public exploit availability, or KEV listing. Treat exposed legacy multi-user systems as higher risk.

Researcher notes

Source data is sparse: no CVSS, CWE, CPE, references, patch details, or exploit-status evidence were provided. Analysis is based on the CVE description and CVE List record only.

Mitigation direction

  • Identify any NetBSD 1.4.x through 1.6 systems.
  • Check NetBSD vendor guidance or historical advisories for supported fixes.
  • Restrict local shell access on affected legacy hosts.
  • Disable or limit unnecessary affected utilities according to vendor guidance.
  • Decommission, isolate, or upgrade unsupported legacy systems where practical.

Validation and detection

  • Confirm operating system version on NetBSD hosts.
  • Inventory presence and permissions of mrinfo, mtrace, and pppd.
  • Determine which local users can execute affected programs.
  • Verify whether vendor-recommended updates or controls are applied.
  • Document unsupported systems requiring isolation or retirement.
