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-2021-43579 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2021-43579/ (Markdown: https://insights.sbomify.com/CVE-2021-43579/index.md)","id":"CVE-2021-43579","markdown":"https://insights.sbomify.com/CVE-2021-43579/index.md","name":"CVE-2021-43579","record":{"aliases":["DEBIAN-CVE-2021-43579","GHSA-999x-mjp8-5gfp","MGASA-2022-0033","SUSE-SU-2022:14877-1","UBUNTU-CVE-2021-43579","openSUSE-SU-2024:11741-1"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HTMLDOC document converter","requires_auth":"none","summary":"A stack-based buffer overflow in HTMLDOC allows remote code execution when a user converts an HTML document linking to a malicious BMP file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"htmldoc","vendor":"htmldoc_project"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/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"}],"description":"A stack-based buffer overflow in image_load_bmp() in HTMLDOC \u003c= 1.9.13 results in remote code execution if the victim converts an HTML document linking to a crafted BMP file.","ecosystems":["SUSE:Subscription Management Tool 11 SP3","openSUSE:Tumbleweed"],"exploits":{"exploitdb":1,"first_seen":"2025-09-16","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-09-16","kind":"exploitdb","ref":"52425","stars":null,"title":"HTMLDOC 1.9.13 - Stack Buffer Overflow"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2021-43579","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux"],"type":"memory_corruption","year":"2021"},"n_packages":2,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-43581"},"packages":[{"ecosystem":"SUSE:Subscription Management Tool 11 SP3","fixed":["1.8.27-170.4.6.1"],"introduced":["0"],"last_affected":[],"package":"htmldoc","purl":"pkg:rpm/suse/htmldoc\u0026distro=Subscription%20Management%20Tool%2011%20SP3","source":"SUSE-SU-2022:14877-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.9.14-1.1"],"introduced":["0"],"last_affected":[],"package":"htmldoc","purl":"pkg:rpm/opensuse/htmldoc\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11741-1"}],"prev":{"headline":"Agent-to-controller security bypass in Jenkins Squash TM Publisher (Squash4Jenkins) Plugin allows writing arbitrary files","id":"CVE-2021-43578"},"products":["n/a"],"published":"2021-11-12","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A stack-based buffer overflow in HTMLDOC allows remote code execution when a user converts an HTML document linking to a malicious BMP file.","url":"https://insights.sbomify.com/CVE-2021-43579/"}
