Security readout for executives and security teams
Plain-English summary
CVE-2025-46398 is a local memory-corruption flaw in fig2dev, associated with xfig/transfig. A crafted or manipulated local input file can trigger a stack overflow in read_objects. The main business concern is integrity impact on systems that process Fig diagram files, especially automated conversion hosts.
Executive priority
Treat this as a moderate operational risk. It is not evidenced as actively exploited, but systems that transform user-provided diagrams should be patched or isolated because the recorded impact is high integrity compromise.
Technical view
The issue is classified as CWE-121 stack-based buffer overflow. CVSS 3.1 is 5.5: local attack vector, low complexity, low privileges, no user interaction, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact recorded.
Likely exposure
Exposure is most likely where transfig or fig2dev is installed on Red Hat Enterprise Linux 6, 7, 8, or 9, or where xfig-related tooling processes local .fig input. Risk increases if conversion workflows accept files from users or external sources.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The described attack requires local input manipulation while running fig2dev. No remote exploitation path is established in the supplied evidence.
Researcher notes
The source bundle identifies read_objects and stack overflow behavior but does not include fixed versions, detailed root cause, or exploit maturity. Validation should focus on package presence and data-flow exposure rather than speculative product scope.
Mitigation direction
- Check Red Hat and Debian guidance for fixed package availability.
- Update transfig, fig2dev, or xfig packages through trusted vendor channels.
- Avoid processing untrusted Fig files until vendor remediation is applied.
- Remove the package from systems that do not need Fig conversion.
- Run conversion jobs with least privilege and filesystem isolation.
Validation and detection
- Inventory systems for installed transfig, fig2dev, or xfig packages.
- Prioritize RHEL 6, 7, 8, and 9 hosts using transfig.
- Identify automated jobs that process user-supplied Fig files.
- Confirm vendor advisory status before marking assets remediated.
- Review package versions after updates against vendor guidance.
