## What is CVE-2016-15045?

CVE-2016-15045 is a high-severity vulnerability in Wuhan Deepin Technology Co., Ltd. Deepin Linux, published on 23 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A local privilege escalation vulnerability exists in lastore-daemon, the system package manager daemon used in Deepin Linux (developed by Wuhan Deepin Technology Co., Ltd.). In versions 0.9.53-1 (Deepin 15.5) and 0.9.66-1 (Deepin 15.7), the D-Bus configuration permits any user in the sudo group to invoke the InstallPackage method without password authentication. By default, the first user created on Deepin is in the sudo group. An attacker with shell access can craft a .deb package containing a malicious post-install script and use dbus-send to install it via lastore-daemon, resulting in arbitrary code execution as root.

Weakness: CWE-306 (Missing Authentication for Critical Functionality), CWE-269 (Improper Privilege Management)

What it is: CVE-2016-15045 is a high-severity vulnerability in Wuhan Deepin Technology Co., Ltd. Deepin Linux, published on 23 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-15045 exists.

Affected product: Wuhan Deepin Technology Co., Ltd. Deepin 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.
