An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of RUSTSEC-2026-0338 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- quinn-proto (crates.io): affected from 0.7.0; fixed in 0.11.18\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/RUSTSEC-2026-0338/ (Markdown: https://insights.sbomify.com/RUSTSEC-2026-0338/index.md)","id":"RUSTSEC-2026-0338","markdown":"https://insights.sbomify.com/RUSTSEC-2026-0338/index.md","name":"RUSTSEC-2026-0338","record":{"aliases":["GHSA-465w-v9q3-7j98"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Rust QUIC library","requires_auth":"none","summary":"Remote attackers can crash applications using quinn-proto by sending zero-length STREAM frames during unordered reads, requiring an upgrade to fix.","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":"When a stream is read in unordered mode (for example through `RecvStream::read(false)` in\nquinn-proto or `read_unordered` in `quinn`), quinn-proto proactively deduplicates received data\nby recording received ranges in a `RangeSet` through its `replace` method. When an incoming\nSTREAM frame carried an empty payload, the `Drop` implementation of the iterator returned by\n`replace` inserted an empty range into the set, violating the invariant that stored ranges are\nnon-empty. Subsequent frames overlapping that region then caused a panic while processing the\nstream.\n\nA remote peer can trigger this with five small STREAM frames (two of them zero-length) once the\napplication has put the stream in unordered-read mode. The default ordered read path is not\naffected.\n\nThe flaw was corrected in 0.11.18 by ignoring empty ranges in `RangeSet::replace`.\n\nThanks to Otto Hermann ([@ojhermann](https://github.com/ojhermann)) for reporting this issue.","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":"Remote peer can panic quinn-proto with zero-length STREAM frames during unordered reads","id":"RUSTSEC-2026-0338","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.11.18"],"introduced":["0.7.0"],"last_affected":[],"package":"quinn-proto","purl":"pkg:cargo/quinn-proto","source":"RUSTSEC-2026-0338"}],"products":null,"published":"2026-09-14","related":[],"sources":[{"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":"Remote attackers can crash applications using quinn-proto by sending zero-length STREAM frames during unordered reads, requiring an upgrade to fix.","url":"https://insights.sbomify.com/RUSTSEC-2026-0338/"}
