# CVE-2014-7300: Denial of service in n/a > Physically proximate attackers can execute arbitrary commands on locked GNOME Shell workstations by exhausting memory via repeated screenshot requests. - **Severity:** High 7.2 (`AV:L/AC:L/Au:N/C:C/I:C/A:C`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 25 Dec 2014 - **Updated:** 6 Aug 2024 - **Also known as:** DEBIAN-CVE-2014-7300, GHSA-gg6w-rmxx-j7xr, MGASA-2014-0501, RHSA-2015:0535, SUSE-SU-2015:0515-1, openSUSE-SU-2024:10441-1 ## What is CVE-2014-7300? CVE-2014-7300 is a high-severity denial of service vulnerability in Redhat Enterprise Linux Desktop, published on 25 Dec 2014. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description GNOME Shell 3.14.x before 3.14.1, when the Screen Lock feature is used, does not limit the aggregate memory consumption of all active PrtSc requests, which allows physically proximate attackers to execute arbitrary commands on an unattended workstation by making many PrtSc requests and leveraging a temporary lock outage, and the resulting temporary shell availability, caused by the Linux kernel OOM killer.

What it is: CVE-2014-7300 is a high-severity denial of service vulnerability in Redhat Enterprise Linux Desktop, published on 25 Dec 2014. 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-2014-7300 in the wild and no public exploit code. Affected product: Redhat Enterprise Linux Desktop. 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.
