## What is CVE-2013-4694?

CVE-2013-4694 is a high-severity memory corruption vulnerability in Nullsoft Winamp, published on 16 Apr 2014. 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

Stack-based buffer overflow in gen_jumpex.dll in Winamp before 5.64 Build 3418 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a package with a long Skin directory name.  NOTE: a second buffer overflow involving a long GUI Search field to ml_local.dll was also reported. However, since it is only exploitable by the user of the application, this issue would not cross privilege boundaries unless Winamp is running under a highly restricted environment such as a kiosk.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)

Check this codebase for CVE-2013-4694 and fix it if it is affected.

What it is: CVE-2013-4694 is a high-severity memory corruption vulnerability in Nullsoft Winamp, published on 16 Apr 2014. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2013-4694 exists.

Affected product: Nullsoft Winamp. 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.
