## What is CVE-2015-7830?

CVE-2015-7830 is a medium-severity memory corruption vulnerability in Oracle Solaris, published on 15 Nov 2015. An attacker can exploit it over the internet without logging in, with no action from the victim.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2015-7830 and fix it if it is affected.

What it is: CVE-2015-7830 is a medium-severity memory corruption vulnerability in Oracle Solaris, published on 15 Nov 2015. 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-2015-7830 in the wild and no public exploit code.

Affected product: Oracle 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.
