An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21808 in the wild and no public exploit code.\n\nAffected product: Accusoft Imagegear. 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-2021-21808/ (Markdown: https://insights.sbomify.com/CVE-2021-21808/index.md)","id":"CVE-2021-21808","markdown":"https://insights.sbomify.com/CVE-2021-21808/index.md","name":"CVE-2021-21808","record":{"aliases":["GHSA-22gx-8v7p-9g9p"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Image processing library","requires_auth":"none","summary":"A heap buffer overflow in Accusoft ImageGear allows attackers to execute arbitrary code or cause denial of service via a crafted PNG file.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"imagegear","vendor":"accusoft"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A memory corruption vulnerability exists in the PNG png_palette_process functionality of Accusoft ImageGear 19.9.
