It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-47737 exists.\n\nAffected packages and fixed versions:\n- trailer (crates.io): affected all versions up to 0.1.2; no fix listed\n- trailer (crates.io): affected all versions up to 0.1.2; no fix listed\n- trailer (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/CVE-2025-47737/ (Markdown: https://insights.sbomify.com/CVE-2025-47737/index.md)","id":"CVE-2025-47737","markdown":"https://insights.sbomify.com/CVE-2025-47737/index.md","name":"CVE-2025-47737","record":{"aliases":["GHSA-6x45-r4pr-5362","RUSTSEC-2025-0163"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Rust trailer crate","requires_auth":"none","summary":"A mishandled zero-size allocation in the Rust trailer crate can cause a null dereference, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"trailer","vendor":"unhandledexpression"}],"cvss":{"score":2.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-762","name":"Mismatched Memory Management Routines"}],"description":"lib.rs in the trailer crate through 0.1.2 for Rust mishandles allocating with a size of zero.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"trailer mishandles allocating with a size of zero","id":"CVE-2025-47737","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":3,"n_references":2,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2025-47748"},"packages":[{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["0.1.2"],"package":"trailer","purl":null,"source":"GHSA-6x45-r4pr-5362"},{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["0.1.2"],"package":"trailer","purl":"pkg:cargo/trailer","source":"GHSA-6x45-r4pr-5362"},{"ecosystem":"crates.io","fixed":[],"introduced":["0.0.0-0"],"last_affected":[],"package":"trailer","purl":"pkg:cargo/trailer","source":"RUSTSEC-2025-0163"}],"prev":{"headline":"libsql-sqlite3-parser crash due to invalid UTF-8 input","id":"CVE-2025-47736"},"products":["trailer"],"published":"2025-05-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-09","vendors":["Geal"]},"summary":"A mishandled zero-size allocation in the Rust trailer crate can cause a null dereference, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-47737/"}
