## What is CVE-2004-0592?

CVE-2004-0592 is a medium-severity vulnerability in Suse Suse Linux, published on 23 Jan 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The tcp_find_option function of the netfilter subsystem for IPv6 in the SUSE Linux 2.6.5 kernel with USAGI patches, when using iptables and TCP options rules, allows remote attackers to cause a denial of service (CPU consumption by infinite loop) via a large option length that produces a negative integer after a casting operation to the char type, a similar flaw to CVE-2004-0626.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2004-0592 and fix it if it is affected.

What it is: CVE-2004-0592 is a medium-severity vulnerability in Suse Suse Linux, published on 23 Jan 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2004-0592 in the wild and no public exploit code.

Affected product: Suse Suse 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.
