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-g753-ghr7-q33w/ (Markdown: https://insights.sbomify.com/GHSA-g753-ghr7-q33w/index.md)","id":"GHSA-g753-ghr7-q33w","markdown":"https://insights.sbomify.com/GHSA-g753-ghr7-q33w/index.md","name":"GHSA-g753-ghr7-q33w","record":{"aliases":["RUSTSEC-2023-0046"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"unknown","non_default_config":false,"product_category":"Rust base library","requires_auth":"none","summary":"A misaligned pointer dereference in cyfs-base can cause undefined behavior, potentially leading to crashes or arbitrary code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The function `ChunkId::new` creates a misaligned pointer by casting mutable pointer of `u8` slice which has alignment 1 to the mutable pointer of `u32` which has alignment 4, and dereference the misaligned pointer leading UB, which should not be allowed in safe function.","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":false,"headline":"cyfs-base vulnerable to misaligned pointer dereference in `ChunkId::new`","id":"GHSA-g753-ghr7-q33w","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["0.6.12"],"package":"cyfs-base","purl":null,"source":"GHSA-g753-ghr7-q33w"},{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["0.6.12"],"package":"cyfs-base","purl":"pkg:cargo/cyfs-base","source":"GHSA-g753-ghr7-q33w"},{"ecosystem":"crates.io","fixed":[],"introduced":["0.0.0-0"],"last_affected":[],"package":"cyfs-base","purl":"pkg:cargo/cyfs-base","source":"RUSTSEC-2023-0046"}],"products":null,"published":"2023-06-15","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":"A misaligned pointer dereference in cyfs-base can cause undefined behavior, potentially leading to crashes or arbitrary code execution.","url":"https://insights.sbomify.com/GHSA-g753-ghr7-q33w/"}
