## What is CVE-2010-20114?

CVE-2010-20114 is a high-severity memory corruption vulnerability in VariCAD EN, published on 21 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

VariCAD EN up to and including version 2010-2.05 is vulnerable to a stack-based buffer overflow when parsing .dwb drawing files. The application fails to properly validate the length of input data embedded in the file, allowing a crafted .dwb file to overwrite critical memory structures. This flaw can be exploited locally by convincing a user to open a malicious file, resulting in arbitrary code execution.

Weakness: CWE-121 (Stack-based Buffer Overflow)

Check this codebase for CVE-2010-20114 and fix it if it is affected.

What it is: CVE-2010-20114 is a high-severity memory corruption vulnerability in VariCAD EN, published on 21 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2010-20114 exists.

Affected product: VariCAD EN. 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.
