Security readout for executives and security teams
Plain-English summary
CVE-2025-3359 is a gnuplot flaw that can cause a segmentation fault, disrupting availability of the local process. Red Hat rates it medium. The business impact is mainly denial of service where gnuplot is installed or used in workflows that process data locally.
Executive priority
Treat as a moderate availability issue. Prioritize environments where gnuplot supports reporting, scientific, engineering, or automated data-processing workflows. It is not currently supported by the sources as an actively exploited or data-compromise vulnerability.
Technical view
The issue is described as a segmentation fault in IO_str_init_static_internal, mapped to CWE-754. CVSS 3.1 is 6.2 with local attack vector, low complexity, no privileges, no user interaction, unchanged scope, and high availability impact only. Red Hat lists RHEL 7 and 8 gnuplot as affected; RHEL 6 status is unknown.
Likely exposure
Exposure is most likely on Linux systems with gnuplot installed, especially Red Hat Enterprise Linux 7 and 8 according to Red Hat’s affected list. Systems without gnuplot, or where it is not reachable by local users or automated jobs, have lower practical exposure.
Exploitation context
The provided sources do not show active exploitation, public weaponization, or CISA KEV listing. The CVSS vector indicates local exploitation affecting availability, not remote code execution or data theft. Practical risk increases if untrusted local inputs are processed by gnuplot in automated pipelines.
Researcher notes
Evidence is limited to vendor and issue-tracking descriptions. The sources identify the crash location and availability impact but do not provide a named fixed version in the supplied bundle. Avoid assuming exploitability beyond local denial of service unless vendor details expand.
Mitigation direction
- Check Red Hat and gnuplot guidance for fixed package availability.
- Prioritize updates on RHEL 7 and 8 systems running gnuplot.
- Limit gnuplot processing of untrusted inputs where feasible.
- Monitor vendor advisories for RHEL 6 status clarification.
Validation and detection
- Inventory systems with the gnuplot package installed.
- Map installed gnuplot instances to RHEL 7 and 8 exposure.
- Review vendor advisories for package status and fixes.
- Check crash logs for gnuplot segmentation faults referencing IO_str_init_static_internal.
