## What is CVE-2024-47539?

CVE-2024-47539 is a high-severity memory corruption vulnerability in Gstreamer Gstreamer, published on 11 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

GStreamer is a library for constructing graphs of media-handling components. An out-of-bounds write vulnerability was identified in the convert_to_s334_1a function in isomp4/qtdemux.c. The vulnerability arises due to a discrepancy between the size of memory allocated to the storage array and the loop condition i * 2 < ccpair_size. Specifically, when ccpair_size is even, the allocated size in storage does not match the loop's expected bounds, resulting in an out-of-bounds write. This bug allows for the overwriting of up to 3 bytes beyond the allocated bounds of the storage array. This vulnerability is fixed in 1.24.10.

Weakness: CWE-787 (Out-of-bounds Write)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-47539 and fix it if it is affected.

What it is: CVE-2024-47539 is a high-severity memory corruption vulnerability in Gstreamer Gstreamer, published on 11 Dec 2024. 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-2024-47539 exists.

Affected product: Gstreamer Gstreamer. 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.
