## What is CVE-2018-14318?

CVE-2018-14318 is a high-severity memory corruption vulnerability in Samsung Galaxy S8, published on 25 Sep 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S8 G950FXXU1AQL5. User interaction is required to exploit this vulnerability in that the target must have their cellular radios enabled. The specific flaw exists within the handling of IPCP headers. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the baseband processor. Was ZDI-CAN-5368.

Weakness: CWE-20 (Improper Input Validation), CWE-121 (Stack-based Buffer Overflow)

Check this codebase for CVE-2018-14318 and fix it if it is affected.

What it is: CVE-2018-14318 is a high-severity memory corruption vulnerability in Samsung Galaxy S8, published on 25 Sep 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2018-14318 in the wild and no public exploit code.

Affected product: Samsung Galaxy S8. 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.
