It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-30354 and fix it if it is affected.\n\nWhat it is: CVE-2021-30354 is a high-severity vulnerability in Amazon Kindle e-reader, published on 1 Sep 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-30354 in the wild and no public exploit code.\n\nAffected product: Amazon Kindle e-reader. 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-2021-30354/ (Markdown: https://insights.sbomify.com/CVE-2021-30354/index.md)","id":"CVE-2021-30354","markdown":"https://insights.sbomify.com/CVE-2021-30354/index.md","name":"CVE-2021-30354","record":{"aliases":["GHSA-66c4-8x32-4mx8"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Amazon Kindle e-reader","requires_auth":"none","summary":"An integer overflow in the Kindle e-reader allows remote code execution via a crafted PDF file, requiring users to update their device firmware.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"checkpoint","cpe":[{"product":"kindle_firmware","vendor":"amazon"}],"cvss":{"score":8.6,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-680","name":"Integer Overflow to Buffer Overflow"}],"description":"Amazon Kindle e-reader prior to and including version 5.13.4 contains an Integer Overflow that leads to a Heap-Based Buffer Overflow in function CJBig2Image::expand() and results in a memory corruption that leads to code execution when parsing a crafted PDF book.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Integer overflow in Amazon Kindle e-reader","id":"CVE-2021-30354","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Amazon Kindle e-reader","id":"CVE-2021-30355"},"packages":[],"prev":{"headline":"Denial of service in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Voice \u0026 Music, Snapdragon Wearables","id":"CVE-2021-30353"},"products":["Amazon Kindle e-reader"],"published":"2021-09-01","related":[{"cvss_score":8.6,"headline":"Privilege escalation in Amazon Kindle e-reader","id":"CVE-2021-30355","kev_date_added":null,"published":"2021-09-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"An integer overflow in the Kindle e-reader allows remote code execution via a crafted PDF file, requiring users to update their device firmware.","url":"https://insights.sbomify.com/CVE-2021-30354/"}
