# CVE-2012-4425: Privilege escalation in n/a > Local attackers can gain privileges and execute arbitrary code in setuid programs using libgio via the DBUS_SYSTEM_BUS_ADDRESS environment variable. - **Severity:** Medium 6.9 (`AV:L/AC:M/Au:N/C:C/I:C/A:C`) - **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:** 18 Sep 2012 - **Updated:** 6 Aug 2024 - **Also known as:** DEBIAN-CVE-2012-4425, GHSA-c77h-vm5q-jc2m, RHSA-2012:1284, openSUSE-SU-2024:10421-1 ## What is CVE-2012-4425? CVE-2012-4425 is a medium-severity vulnerability in n/a, published on 18 Sep 2012. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description libgio, when used in setuid or other privileged programs in spice-gtk and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: it could be argued that this is a vulnerability in the applications that do not cleanse environment variables, not in libgio itself.

Apply the vendor's patch. ## Is CVE-2012-4425 being exploited? There is no known exploitation of CVE-2012-4425 in the wild and no public exploit code. Public exploit code: - libdbus - 'DBUS_SYSTEM_BUS_ADDRESS' Local Privilege Escalation (exploitdb) ## Fix prompt for AI coding agents ```text Check this codebase for CVE-2012-4425 and fix it if it is affected. What it is: CVE-2012-4425 is a medium-severity vulnerability in n/a, published on 18 Sep 2012. 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-2012-4425 in the wild and no public exploit code. Affected product: n/a. 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.
