Security readout for executives and security teams
Plain-English summary
CVE-2025-31179 is a gnuplot crash flaw. A problem in xstrftime() can trigger a segmentation fault, affecting availability. The published CVSS is 6.2 medium. Current sources do not show data theft, privilege escalation, or confirmed active exploitation.
Executive priority
Treat as a moderate availability risk. Prioritize systems where gnuplot supports production reporting, scientific processing, or automated pipelines. Escalate if vendor guidance confirms affected deployed versions or if crashes are observed in business-critical workflows.
Technical view
The flaw is described as a NULL pointer dereference class issue in gnuplot’s xstrftime() handling, mapped to CWE-476. The CVSS vector is local, low complexity, no privileges, no user interaction, with high availability impact only. Red Hat lists RHEL 6, 7, and 8 status as unknown in the provided data.
Likely exposure
Exposure is most relevant where gnuplot is installed and can be invoked locally or through automation. Risk increases if applications pass untrusted plotting or time-format data into gnuplot. Affected version and fixed-version details are incomplete in the provided sources.
Exploitation context
No CISA KEV listing or cited source confirms active exploitation. The impact described is denial of service through a crash, not code execution. The CVSS vector indicates local attack conditions, so internet-exposed risk depends on whether another service exposes gnuplot processing.
Researcher notes
Evidence currently supports a crash in xstrftime(), but public details in the bundle are limited. Do not assume exploitability beyond denial of service. Key gaps are exact affected upstream versions, fixed commits or releases, and downstream package status for Red Hat releases.
Mitigation direction
- Inventory systems and applications using gnuplot.
- Check Red Hat and gnuplot advisories for fixed packages.
- Update gnuplot when vendor-confirmed fixes are available.
- Limit gnuplot processing of untrusted input.
- Monitor workloads that call gnuplot for abnormal crashes.
Validation and detection
- Identify installed gnuplot packages and versions.
- Review vendor status for the operating system release.
- Confirm whether automated jobs invoke gnuplot.
- Check logs for recent gnuplot segmentation faults.
- Track Red Hat Bugzilla and SourceForge issue updates.

NULL Pointer Dereference
NULL Pointer Dereference represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
