# CVE-2015-8325: Privilege escalation in n/a > Local attackers can gain privileges via environment manipulation in OpenSSH when UseLogin and PAM are configured, requiring a patch. - **Severity:** High 7.8 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 1 May 2016 - **Updated:** 22 May 2026 - **Also known as:** ALPINE-CVE-2015-8325, DEBIAN-CVE-2015-8325, DSA-3550-1, GHSA-729x-x825-x8jf, RHSA-2016:2588, RHSA-2017:0641, UBUNTU-CVE-2015-8325 ## What is CVE-2015-8325? CVE-2015-8325 is a high-severity vulnerability in Canonical Ubuntu Linux, published on 1 May 2016. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable.

What it is: CVE-2015-8325 is a high-severity vulnerability in Canonical Ubuntu Linux, published on 1 May 2016. 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-2015-8325 in the wild and no public exploit code. Affected product: Canonical Ubuntu Linux. 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.
