An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-3406 in the wild and no public exploit code.\n\nAffected product: Nothings stb. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-3406/ (Markdown: https://insights.sbomify.com/CVE-2025-3406/index.md)","id":"CVE-2025-3406","markdown":"https://insights.sbomify.com/CVE-2025-3406/index.md","name":"CVE-2025-3406","record":{"aliases":["DEBIAN-CVE-2025-3406","GHSA-7249-98jq-4p25","UBUNTU-CVE-2025-3406"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"stb header library","requires_auth":"none","summary":"An out-of-bounds read in the stb library's tileset builder allows remote attackers to cause denial of service or disclose memory contents.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"stb_image.h","vendor":"nothings"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability was found in Nothings stb up to f056911.
