An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-mcrf-7hf9-f6q5 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rmpv (crates.io): affected all versions; fixed in 0.4.2\n- rmpv (crates.io): affected all versions; fixed in 0.4.2\n- rmpv (crates.io): affected from 0.0.0-0; fixed in 0.4.2\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/GHSA-mcrf-7hf9-f6q5/ (Markdown: https://insights.sbomify.com/GHSA-mcrf-7hf9-f6q5/index.md)","id":"GHSA-mcrf-7hf9-f6q5","markdown":"https://insights.sbomify.com/GHSA-mcrf-7hf9-f6q5/index.md","name":"GHSA-mcrf-7hf9-f6q5","record":{"aliases":["RUSTSEC-2017-0006"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust msgpack library","requires_auth":"none","summary":"An attacker can cause denial of service by sending small msgpack messages that trigger excessive memory allocation in the Rust library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Affected versions of this crate pre-allocate memory on deserializing raw\nbuffers without checking whether there is sufficient data available.\n\nThis allows an attacker to do denial-of-service attacks by sending small\nmsgpack messages that allocate gigabytes of memory.","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Unchecked vector pre-allocation","id":"GHSA-mcrf-7hf9-f6q5","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2017"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.4.2"],"introduced":["0"],"last_affected":[],"package":"rmpv","purl":null,"source":"GHSA-mcrf-7hf9-f6q5"},{"ecosystem":"crates.io","fixed":["0.4.2"],"introduced":["0"],"last_affected":[],"package":"rmpv","purl":"pkg:cargo/rmpv","source":"GHSA-mcrf-7hf9-f6q5"},{"ecosystem":"crates.io","fixed":["0.4.2"],"introduced":["0.0.0-0"],"last_affected":[],"package":"rmpv","purl":"pkg:cargo/rmpv","source":"RUSTSEC-2017-0006"}],"products":null,"published":"2017-11-21","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can cause denial of service by sending small msgpack messages that trigger excessive memory allocation in the Rust library.","url":"https://insights.sbomify.com/GHSA-mcrf-7hf9-f6q5/"}
