It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-3973 in the wild and no public exploit code.\n\nAffected product: Comodo Antivirus. 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-2019-3973/ (Markdown: https://insights.sbomify.com/CVE-2019-3973/index.md)","id":"CVE-2019-3973","markdown":"https://insights.sbomify.com/CVE-2019-3973/index.md","name":"CVE-2019-3973","record":{"aliases":["GHSA-mpmv-49pr-6hch"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Comodo Antivirus","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash or potentially execute code via an out-of-bounds write in the CmdGuard.sys driver.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"antivirus","vendor":"comodo"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Comodo Antivirus versions 11.0.0.6582 and below are vulnerable to Denial of Service affecting CmdGuard.sys via its filter port \"cmdServicePort\". A low privileged process can crash CmdVirth.exe to decrease the port's connection count followed by process hollowing a CmdVirth.exe instance with malicious code to obtain a handle to \"cmdServicePort\". Once this occurs, a specially crafted message can be sent to \"cmdServicePort\" using \"FilterSendMessage\" API. This can trigger an out-of-bounds write if lpOutBuffer parameter in FilterSendMessage API is near the end of specified buffer bounds. The crash occurs when the driver performs a memset operation which uses a size beyond the size of buffer specified, causing kernel crash.","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":"Memory corruption in Comodo Antivirus","id":"CVE-2019-3973","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Tenable Nessus","id":"CVE-2019-3974"},"packages":[],"prev":{"headline":"Denial of service in Comodo Antivirus","id":"CVE-2019-3972"},"products":["Comodo Antivirus"],"published":"2019-07-17","related":[{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2022-34008","kev_date_added":null,"published":"2022-06-21"},{"cvss_score":7.8,"headline":"Privilege escalation in Comodo Antivirus","id":"CVE-2019-3969","kev_date_added":null,"published":"2019-07-17"},{"cvss_score":7.1,"headline":"Privilege escalation in n/a","id":"CVE-2019-14270","kev_date_added":null,"published":"2019-07-25"},{"cvss_score":5.5,"headline":"Missing authorization in Comodo Antivirus","id":"CVE-2019-3970","kev_date_added":null,"published":"2019-07-17"},{"cvss_score":5.5,"headline":"Null dereference in Comodo Antivirus","id":"CVE-2019-3971","kev_date_added":null,"published":"2019-07-17"},{"cvss_score":5.5,"headline":"Denial of service in Comodo Antivirus","id":"CVE-2019-3972","kev_date_added":null,"published":"2019-07-17"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A local attacker can trigger a kernel crash or potentially execute code via an out-of-bounds write in the CmdGuard.sys driver.","url":"https://insights.sbomify.com/CVE-2019-3973/"}
