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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-21147 exists.\n\nAffected product: ESTsoft Alyac. 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-2022-21147/ (Markdown: https://insights.sbomify.com/CVE-2022-21147/index.md)","id":"CVE-2022-21147","markdown":"https://insights.sbomify.com/CVE-2022-21147/index.md","name":"CVE-2022-21147","record":{"aliases":["GHSA-6r55-j877-x6cq"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ESTsoft Alyac antivirus","requires_auth":"low_privilege","summary":"An out-of-bounds read in ESTsoft Alyac allows attackers to cause denial of service via a crafted PE file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"alyac","vendor":"estsoft"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-823","name":"Use of Out-of-range Pointer Offset"}],"description":"An out of bounds read vulnerability exists in the malware scan functionality of ESTsoft Alyac 2.5.7.7.
