## What is CVE-2017-15288?

CVE-2017-15288 is a high-severity vulnerability in n/a, published on 15 Nov 2017. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The compilation daemon in Scala before 2.10.7, 2.11.x before 2.11.12, and 2.12.x before 2.12.4 uses weak permissions for private files in /tmp/scala-devel/${USER:shared}/scalac-compile-server-port, which allows local users to write to arbitrary class files and consequently gain privileges.

Weakness: CWE-732 (Incorrect Permission Assignment for Critical Resource)

- org.scala-lang:scala-compiler (Maven): affected all versions; fixed in 2.10.7
- org.scala-lang:scala-compiler (Maven): affected from 2.11.0; fixed in 2.11.12

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.
