## What is CVE-2018-1171?

CVE-2018-1171 is a high-severity memory corruption vulnerability in Oracle Solaris, published on 19 Mar 2018. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Joyent SmartOS release-20170803-20170803T064301Z. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DTrace DOF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of the host OS. Was ZDI-CAN-5106.

Weakness: CWE-787 (Out-of-bounds Write)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2018-1171 and fix it if it is affected.

What it is: CVE-2018-1171 is a high-severity memory corruption vulnerability in Oracle Solaris, published on 19 Mar 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-1171 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.
