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-2019-12798 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-2019-12798/ (Markdown: https://insights.sbomify.com/CVE-2019-12798/index.md)","id":"CVE-2019-12798","markdown":"https://insights.sbomify.com/CVE-2019-12798/index.md","name":"CVE-2019-12798","record":{"aliases":["GHSA-pccm-w2w7-v4p2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript engine library","requires_auth":"none","summary":"An integer overflow in the regular expression parser of the MuJS JavaScript engine can lead to a denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mujs","vendor":"artifex"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-185","name":"Incorrect Regular Expression"}],"description":"An issue was discovered in Artifex MuJS 1.0.5. regcompx in regexp.c does not restrict regular expression program size, leading to an overflow of the parsed syntax list size.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Integer overflow in n/a","id":"CVE-2019-12798","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Shopware Insecure Deserialization Vulnerability","id":"CVE-2019-12799"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2019-12797"},"products":["n/a"],"published":"2019-06-13","related":[{"cvss_score":10,"headline":"Use after free in MuJS","id":"CVE-2021-33796","kev_date_added":null,"published":"2023-07-07"},{"cvss_score":9.8,"headline":"Integer overflow in mujs","id":"CVE-2021-33797","kev_date_added":null,"published":"2023-04-17"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-45005","kev_date_added":null,"published":"2022-02-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-11411","kev_date_added":null,"published":"2019-04-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-10133","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-10141","kev_date_added":null,"published":"2017-01-13"}],"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":"An integer overflow in the regular expression parser of the MuJS JavaScript engine can lead to a denial of service.","url":"https://insights.sbomify.com/CVE-2019-12798/"}
