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-w7hm-hmxv-pvhf in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- hpack (crates.io): affected all versions up to 0.3.0; no fix listed\n- hpack (crates.io): affected all versions up to 0.3.0; no fix listed\n- hpack (crates.io): affected from 0.0.0-0; 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/GHSA-w7hm-hmxv-pvhf/ (Markdown: https://insights.sbomify.com/GHSA-w7hm-hmxv-pvhf/index.md)","id":"GHSA-w7hm-hmxv-pvhf","markdown":"https://insights.sbomify.com/GHSA-w7hm-hmxv-pvhf/index.md","name":"GHSA-w7hm-hmxv-pvhf","record":{"aliases":["RUSTSEC-2023-0085"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust HPACK decoder","requires_auth":"none","summary":"An attacker can cause a denial of service by sending malformed HPACK data that triggers a panic in the decoder.","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":"Due to insufficient checking of input data, decoding certain data sequences can\nlead to _Decoder::decode_ panicking rather than returning an error.\n\nExample code that triggers this vulnerability looks like this:\n\n```rust\nuse hpack::Decoder;\n\npub fn main() {\n  let input = \u0026[0x3f];\n  let mut decoder = Decoder::new();\n  let _ = decoder.decode(input);\n}\n```\n\nhpack is unmaintained.
