## What is CVE-2004-0791?

CVE-2004-0791 is a medium-severity denial of service vulnerability in Sun Solaris, published on 13 Apr 2005. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Multiple TCP/IP and ICMP implementations allow remote attackers to cause a denial of service (network throughput reduction for TCP connections) via a blind throughput-reduction attack using spoofed Source Quench packets, aka the "ICMP Source Quench attack."  NOTE: CVE-2004-0790, CVE-2004-0791, and CVE-2004-1060 have been SPLIT based on different attacks; CVE-2005-0065, CVE-2005-0066, CVE-2005-0067, and CVE-2005-0068 are related identifiers that are SPLIT based on the underlying vulnerability.  While CVE normally SPLITs based on vulnerability, the attack-based identifiers exist due to the variety and number of affected implementations and solutions that address the attacks instead of the underlying vulnerabilities.

## Which versions are affected by CVE-2004-0791?

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2004-0791 and fix it if it is affected.

What it is: CVE-2004-0791 is a medium-severity denial of service vulnerability in Sun Solaris, published on 13 Apr 2005. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2004-0791 exists.

Affected product: Sun Solaris. 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.
