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-2020-28248 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- png-img (npm): affected all versions; fixed in 3.1.0\n- png-img (npm): affected all versions; fixed in 3.1.0\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-2020-28248/ (Markdown: https://insights.sbomify.com/CVE-2020-28248/index.md)","id":"CVE-2020-28248","markdown":"https://insights.sbomify.com/CVE-2020-28248/index.md","name":"CVE-2020-28248","record":{"aliases":["GHSA-q5wr-fvpq-p67g"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PNG image library","requires_auth":"none","summary":"An integer overflow in the png-img library leads to heap buffer overflow, allowing remote code execution via crafted PNG files.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"png-img","vendor":"png-img_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow in the PngImg::InitStorage_() function of png-img before 3.1.0 leads to an under-allocation of heap memory and subsequently an exploitable heap-based buffer overflow when loading a crafted PNG file.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer Overflow in png-img","id":"CVE-2020-28248","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"integer_overflow","year":"2020"},"n_packages":2,"n_references":4,"next":{"headline":"Cross-site scripting in Joplin","id":"CVE-2020-28249"},"packages":[{"ecosystem":"npm","fixed":["3.1.0"],"introduced":["0"],"last_affected":[],"package":"png-img","purl":null,"source":"GHSA-q5wr-fvpq-p67g"},{"ecosystem":"npm","fixed":["3.1.0"],"introduced":["0"],"last_affected":[],"package":"png-img","purl":"pkg:npm/png-img","source":"GHSA-q5wr-fvpq-p67g"}],"prev":{"headline":"Argument injection in lettre","id":"CVE-2020-28247"},"products":["n/a"],"published":"2021-02-19","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":"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":"2024-08-04","vendors":["n/a"]},"summary":"An integer overflow in the png-img library leads to heap buffer overflow, allowing remote code execution via crafted PNG files.","url":"https://insights.sbomify.com/CVE-2020-28248/"}
