Security readout for executives and security teams
Plain-English summary
CVE-2025-31177 is a heap buffer overflow in gnuplot’s utf8_copy_one function. The published impact is denial of service, not data theft or privilege escalation. It is rated medium by the source bundle, with local, low-complexity exploitation requiring a low-privileged local context. No cited source indicates active exploitation.
Executive priority
Handle in normal vulnerability management cycles, with faster attention for shared Linux systems or automated data-processing environments. Current evidence supports moderate urgency because impact is availability-only and no active exploitation is cited.
Technical view
The issue is classified as CWE-122 heap-based buffer overflow in gnuplot. The CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, score 5.5. Red Hat tracks potential exposure for RHEL 6, 7, and 8, but status is listed as unknown in the provided data.
Likely exposure
Exposure is most relevant where gnuplot is installed and usable by local users or automated workflows. The provided affected-version data is incomplete: gnuplot is listed with version “0,” and Red Hat product status is unknown. Confirm package presence and vendor-specific applicability.
Exploitation context
The CVSS vector indicates local access and low privileges are required, with availability impact only. There is no KEV listing and no cited source in the bundle reports exploitation in the wild. Treat this as a stability and service-disruption risk until vendor details clarify scope.
Researcher notes
Key gaps are affected upstream versions, fixed version, and vendor remediation status. The Red Hat entries for RHEL 6, 7, and 8 are marked unknown in the provided data. Avoid assuming exploitability beyond the local, low-privilege, availability-only CVSS characterization.
Mitigation direction
- Check Red Hat and gnuplot guidance for fixed packages or official workarounds.
- Inventory systems and workflows where gnuplot is installed or invoked automatically.
- Prioritize remediation on shared systems or services processing user-supplied plotting input.
- Monitor the Red Hat CVE page, Bugzilla, and SourceForge issue for status changes.
Validation and detection
- Confirm whether gnuplot is installed on managed Linux assets.
- Map installed packages to Red Hat or upstream advisories when available.
- Review automated jobs that invoke gnuplot with externally supplied input.
- Track whether vendor status changes from unknown to affected or fixed.
