## What is CVE-2007-4998?

CVE-2007-4998 is a medium-severity path traversal vulnerability in Linux kernel, published on 31 Jan 2008. 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

cp, when running with an option to preserve symlinks on multiple OSes, allows local, user-assisted attackers to overwrite arbitrary files via a symlink attack using crafted directories containing multiple source files that are copied to the same destination.

Weakness: CWE-59 (Improper Link Resolution Before File Access)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2007-4998 and fix it if it is affected.

What it is: CVE-2007-4998 is a medium-severity path traversal vulnerability in Linux kernel, published on 31 Jan 2008. 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: There is no known exploitation of CVE-2007-4998 in the wild and no public exploit code.

Affected product: Linux kernel. 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.
