## What is CVE-2016-8389?

CVE-2016-8389 is a high-severity vulnerability in Iceni Argus, published on 28 Feb 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

An exploitable integer-overflow vulnerability exists within Iceni Argus. When it attempts to convert a malformed PDF to XML, it will attempt to convert each character from a font into a polygon and then attempt to rasterize these shapes. As the application attempts to iterate through the rows and initializing the polygon shape in the buffer, it will write outside of the bounds of said buffer. This can lead to code execution under the context of the account running it.

Weakness: CWE-190 (Integer Overflow or Wraparound)

Check this codebase for CVE-2016-8389 and fix it if it is affected.

What it is: CVE-2016-8389 is a high-severity vulnerability in Iceni Argus, published on 28 Feb 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2016-8389 in the wild and no public exploit code.

Affected product: Iceni Argus. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
