It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2024-8375 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dm-reverb (PyPI): affected all versions up to 0.14.0; no fix listed\n- dm-reverb (PyPI): affected all versions up to 0.14.0; no fix listed\n- dm-reverb (PyPI): affected all versions up to 0.14.0; no fix listed\n- dm-reverb-nightly (PyPI): affected all versions up to 0.15.0.dev20240214; no fix listed\n- dm-reverb-nightly (PyPI): affected all versions up to 0.15.0.dev20240214; no fix listed\n- dm-reverb-nightly (PyPI): affected all versions up to 0.15.0.dev20240214; no fix listed\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-8375/ (Markdown: https://insights.sbomify.com/CVE-2024-8375/index.md)","id":"CVE-2024-8375","markdown":"https://insights.sbomify.com/CVE-2024-8375/index.md","name":"CVE-2024-8375","record":{"aliases":["GHSA-w69q-w4h4-2fx8","PYSEC-2026-1306","PYSEC-2026-2452"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Reverb library","requires_auth":"low_privilege","summary":"An attacker can achieve remote code execution by exploiting a use-after-free vulnerability in the Reverb library via crafted tensor data.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"reverb","vendor":"google"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:L/VI:H/VA:N/SC:L/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"There exists a use after free vulnerability in Reverb. Reverb supports the VARIANT datatype, which is supposed to represent an arbitrary object in C++. When a tensor proto of type VARIANT is unpacked, memory is first allocated to store the entire tensor, and a ctor is called on each instance. Afterwards, Reverb copies the content in tensor_content to the previously mentioned pre-allocated memory, which results in the bytes in tensor_content overwriting the vtable pointers of all the objects which were previously allocated. Reverb exposes 2 relevant gRPC endpoints: InsertStream and SampleStream. The attacker can insert this stream into the server’s database, then when the client next calls SampleStream they will unpack the tensor into RAM, and when any method on that object is called (including its destructor) the attacker gains control of the Program Counter.
