## What is CVE-2004-0994?

CVE-2004-0994 is a critical vulnerability in Debian Debian Linux, published on 15 Dec 2004. 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

Multiple integer overflows in xzgv 0.8 and earlier allow remote attackers to execute arbitrary code via images with large width and height values, which trigger a heap-based buffer overflow, as demonstrated in the read_prf_file function in readprf.c.  NOTE: CVE-2004-0994 and CVE-2004-1095 identify sets of bugs that only partially overlap, despite having the same developer.  Therefore, they should be regarded as distinct.

## Which versions are affected by CVE-2004-0994?

It affects 3 products.


Products: Debian Debian Linux, Zgv Xzgv Image Viewer, Zgv Zgv Image Viewer.

## How do I fix CVE-2004-0994?

Upgrade to a fixed version.

## Is CVE-2004-0994 being exploited?

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2004-0994 and fix it if it is affected.

What it is: CVE-2004-0994 is a critical vulnerability in Debian Debian Linux, published on 15 Dec 2004. 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-2004-0994 in the wild and no public exploit code.

Affected product: Debian Debian Linux. 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.
