# CVE-2012-3445: Memory corruption in n/a > Remote authenticated users can crash the libvirtd daemon via a crafted RPC command, causing a denial of service. - **Severity:** Low 3.5 (`AV:N/AC:M/Au:S/C:N/I:N/A:P`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 7 Aug 2012 - **Updated:** 6 Aug 2024 - **Also known as:** DEBIAN-CVE-2012-3445, GHSA-65xv-xg43-h8gj, RHSA-2012:1202 ## What is CVE-2012-3445? CVE-2012-3445 is a low-severity memory corruption vulnerability in Redhat Libvirt, published on 7 Aug 2012. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description The virTypedParameterArrayClear function in libvirt 0.9.13 does not properly handle virDomain* API calls with typed parameters, which might allow remote authenticated users to cause a denial of service (libvirtd crash) via an RPC command with nparams set to zero, which triggers an out-of-bounds read or a free of an invalid pointer.

What it is: CVE-2012-3445 is a low-severity memory corruption vulnerability in Redhat Libvirt, published on 7 Aug 2012. Any signed-in user can exploit it over the network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2012-3445 in the wild and no public exploit code. Affected product: Redhat Libvirt. 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.
