## What is CVE-2020-14370?

CVE-2020-14370 is a medium-severity vulnerability in Fedoraproject Fedora, published on 23 Sep 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An information disclosure vulnerability was found in containers/podman in versions before 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first container will get leaked into subsequent containers. An attacker who has control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables.

Weakness: CWE-212 (Improper Removal of Sensitive Information Before Storage or Transfer)

What it is: CVE-2020-14370 is a medium-severity vulnerability in Fedoraproject Fedora, published on 23 Sep 2020. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-14370 in the wild and no public exploit code.

Affected packages and fixed versions:
- github.com/containers/podman/v2 (Go): affected all versions; fixed in 2.0.5
- github.com/containers/podman/v2 (Go): affected all versions; fixed in 2.0.5

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.
