CVE-2023-37327 GStreamer FLAC File Parsing Integer Overflow Remote Code Execution Vulnerability
High 7.6
Published
Updated
Check this codebase for CVE-2023-37327 and fix it if it is affected.
What it is: CVE-2023-37327 is a high-severity vulnerability in Gstreamer Gstreamer, published on 3 May 2024. 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-2023-37327 in the wild and no public exploit code.
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.

What is CVE-2023-37327?
CVE-2023-37327 is a high-severity vulnerability in Gstreamer Gstreamer, published on 3 May 2024. 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
GStreamer FLAC File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of FLAC audio files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20775.
Weakness: CWE-190
