# CVE-2019-7443: Privilege escalation in n/a > KDE KAuth allows arbitrary plugin code execution as root via DBus, enabling privilege escalation for attackers exploiting plugin vulnerabilities. - **Severity:** High 8.1 (`CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 7 May 2019 - **Updated:** 4 Aug 2024 - **Also known as:** DEBIAN-CVE-2019-7443, GHSA-wmpm-pm59-7mfw, UBUNTU-CVE-2019-7443, USN-6035-1, openSUSE-SU-2019:0242-1, openSUSE-SU-2019:0247-1, openSUSE-SU-2019:1051-1, openSUSE-SU-2019:1277-1 ## What is CVE-2019-7443? CVE-2019-7443 is a high-severity vulnerability in Fedoraproject Fedora, published on 7 May 2019. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description KDE KAuth before 5.55 allows the passing of parameters with arbitrary types to helpers running as root over DBus via DBusHelperProxy.cpp. Certain types can cause crashes, and trigger the decoding of arbitrary images with dynamically loaded plugins. In other words, KAuth unintentionally causes this plugin code to run as root, which increases the severity of any possible exploitation of a plugin vulnerability.

What it is: CVE-2019-7443 is a high-severity vulnerability in Fedoraproject Fedora, published on 7 May 2019. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2019-7443 in the wild and no public exploit code. Affected product: Fedoraproject Fedora. 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.
