CVE-2016-8388 Iceni CVE debrief
CVE-2016-8388 is a high-severity vulnerability in Iceni Argus. When the product converts a malformed PDF to XML, it can trust an attacker-influenced index from a font object and use it to write a font name into an object array, resulting in an arbitrary heap overwrite. The published CVSS score is 7.8, and the NVD vector indicates local access with user interaction required.

Who should care
Teams running Iceni Argus 6.6.04 or similar PDF-to-XML processing workflows, especially where untrusted or externally supplied PDFs are handled. Security and operations teams should pay attention because the issue is triggered during document conversion and can affect systems that process adversarial files.
Technical summary
NVD lists CVE-2016-8388 against Iceni Argus 6.6.04 and classifies it as CWE-125. The vulnerability is described as an exploitable arbitrary heap-overwrite in the PDF-to-XML conversion path: a malformed PDF can cause Argus to explicitly trust an index from a font object and use it to write the font name to a single object in an array of objects. The CVSS 3.1 vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating high potential impact but requiring user interaction.
Defensive priority
High, but context-dependent. The severity and impact are high, yet the attack path requires local execution context and user interaction. Prioritize remediation if Argus is used in production document pipelines or on endpoints that may open untrusted PDFs.
Recommended defensive actions
- Identify all installations of Iceni Argus, with special attention to version 6.6.04.
- Treat untrusted PDFs as hostile and restrict who can submit files for conversion.
- Isolate the conversion workflow in a sandboxed or least-privilege environment.
- Remove or replace the affected version if no vendor fix is available.
- Monitor for vendor advisories and validate whether a patched Argus release exists before continuing production use.
