### Official description

Huawei DP300 V500R002C00, Secospace USG6300 V500R001C00, V500R001C20, V500R001C30, V500R001C50, Secospace USG6500 V500R001C00, V500R001C20, V500R001C30, V500R001C50, Secospace USG6600 V500R001C00, V500R001C20, V500R001C30, V500R001C50, TP3206 V100R002C00, VP9660 V500R002C00, V500R002C10 have a resource exhaustion vulnerability. The software does not process certain field of H.323 message properly, a remote unauthenticated attacker could send crafted H.323 message to the device, successful exploit could cause certain service unavailable since the stack memory is exhausted.

Weakness: CWE-400 (Uncontrolled Resource Consumption)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2017-17166 and fix it if it is affected.

What it is: CVE-2017-17166 is a medium-severity denial of service vulnerability in Huawei Dp300 Firmware, published on 15 Feb 2018. 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-2017-17166 in the wild and no public exploit code.

Affected product: Huawei Dp300 Firmware. 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.
