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-2018-21232 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-21232/ (Markdown: https://insights.sbomify.com/CVE-2018-21232/index.md)","id":"CVE-2018-21232","markdown":"https://insights.sbomify.com/CVE-2018-21232/index.md","name":"CVE-2018-21232","record":{"aliases":["AZL-7337","DEBIAN-CVE-2018-21232","ECHO-4fc2-67bd-0a7a","GHSA-pgr8-gpgg-9j5m","MGASA-2021-0299","SUSE-SU-2023:3353-1","UBUNTU-CVE-2018-21232"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"re2c lexer generator","requires_auth":"none","summary":"An attacker can cause a denial of service via stack consumption in the re2c lexer generator due to uncontrolled recursion.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"re2c","vendor":"re2c"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"re2c before 2.0 has uncontrolled recursion that causes stack consumption in find_fixed_tags.","ecosystems":["SUSE:Linux Enterprise Module for Basesystem 15 SP4","SUSE:Linux Enterprise Module for Basesystem 15 SP5","SUSE:Manager Proxy 4.2","SUSE:Manager Server 4.2","openSUSE:Leap 15.4","openSUSE:Leap 15.5"],"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":"Denial of service in n/a","id":"CVE-2018-21232","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":6,"n_references":3,"next":{"headline":"Out-of-bounds read in TensorFlow possibly causing disclosure of the contents of process memory.","id":"CVE-2018-21233"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15 SP4","fixed":["1.0.3-150000.3.3.1"],"introduced":["0"],"last_affected":[],"package":"re2c","purl":"pkg:rpm/suse/re2c\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015%20SP4","source":"SUSE-SU-2023:3353-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15 SP5","fixed":["1.0.3-150000.3.3.1"],"introduced":["0"],"last_affected":[],"package":"re2c","purl":"pkg:rpm/suse/re2c\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015%20SP5","source":"SUSE-SU-2023:3353-1"},{"ecosystem":"SUSE:Manager Proxy 4.2","fixed":["1.0.3-150000.3.3.1"],"introduced":["0"],"last_affected":[],"package":"re2c","purl":"pkg:rpm/suse/re2c\u0026distro=SUSE%20Manager%20Proxy%204.2","source":"SUSE-SU-2023:3353-1"},{"ecosystem":"SUSE:Manager Server 4.2","fixed":["1.0.3-150000.3.3.1"],"introduced":["0"],"last_affected":[],"package":"re2c","purl":"pkg:rpm/suse/re2c\u0026distro=SUSE%20Manager%20Server%204.2","source":"SUSE-SU-2023:3353-1"},{"ecosystem":"openSUSE:Leap 15.4","fixed":["1.0.3-150000.3.3.1"],"introduced":["0"],"last_affected":[],"package":"re2c","purl":"pkg:rpm/opensuse/re2c\u0026distro=openSUSE%20Leap%2015.4","source":"SUSE-SU-2023:3353-1"},{"ecosystem":"openSUSE:Leap 15.5","fixed":["1.0.3-150000.3.3.1"],"introduced":["0"],"last_affected":[],"package":"re2c","purl":"pkg:rpm/opensuse/re2c\u0026distro=openSUSE%20Leap%2015.5","source":"SUSE-SU-2023:3353-1"}],"prev":{"headline":"Misconfiguration in n/a","id":"CVE-2018-21231"},"products":["n/a"],"published":"2020-04-29","related":[{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2022-23901","kev_date_added":null,"published":"2022-03-29"}],"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":"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":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can cause a denial of service via stack consumption in the re2c lexer generator due to uncontrolled recursion.","url":"https://insights.sbomify.com/CVE-2018-21232/"}
