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-2018-13347/ (Markdown: https://insights.sbomify.com/CVE-2018-13347/index.md)","id":"CVE-2018-13347","markdown":"https://insights.sbomify.com/CVE-2018-13347/index.md","name":"CVE-2018-13347","record":{"aliases":["DEBIAN-CVE-2018-13347","GHSA-3mjj-mr4f-qxmx","PYSEC-2018-89","UBUNTU-CVE-2018-13347"],"analysis":null,"analysis_generated_by":null,"assigner":"mitre","cpe":[{"product":"mercurial","vendor":"mercurial"}],"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-190","name":"Integer Overflow or Wraparound"}],"description":"mpatch.c in Mercurial before 4.6.1 mishandles integer addition and subtraction, aka OVE-20180430-0002.","ecosystems":["PyPI"],"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":"Mercurial mishandles integer addition and subtraction","id":"CVE-2018-13347","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":null,"year":"2018"},"n_packages":3,"n_references":5,"next":{"headline":"Mercurial Improper Input Validation vulnerability","id":"CVE-2018-13348"},"packages":[{"ecosystem":"PyPI","fixed":["4.6.1"],"introduced":["0"],"last_affected":[],"package":"mercurial","purl":null,"source":"GHSA-3mjj-mr4f-qxmx"},{"ecosystem":"PyPI","fixed":["4.6.1"],"introduced":["0"],"last_affected":[],"package":"mercurial","purl":"pkg:pypi/mercurial","source":"GHSA-3mjj-mr4f-qxmx"},{"ecosystem":"PyPI","fixed":["4.6.1"],"introduced":["0"],"last_affected":[],"package":"mercurial","purl":"pkg:pypi/mercurial","source":"PYSEC-2018-89"}],"prev":{"headline":"Mercurial Improper Input Validation vulnerability","id":"CVE-2018-13346"},"products":["n/a"],"published":"2018-07-06","related":[{"cvss_score":9.1,"headline":"Mercurial Out-of-bounds Read vulnerability","id":"CVE-2018-17983","kev_date_added":null,"published":"2018-10-04"},{"cvss_score":7.5,"headline":"Mercurial Improper Input Validation vulnerability","id":"CVE-2018-13346","kev_date_added":null,"published":"2018-07-06"},{"cvss_score":7.5,"headline":"Mercurial Improper Input Validation vulnerability","id":"CVE-2018-13348","kev_date_added":null,"published":"2018-07-06"},{"cvss_score":7.5,"headline":"Mercurial vulnerable to arbitrary command execution via a crafted repository name in a clone command","id":"CVE-2014-9462","kev_date_added":null,"published":"2015-03-31"},{"cvss_score":6.8,"headline":"Mercurial Directory traversal vulnerability","id":"CVE-2008-2942","kev_date_added":null,"published":"2008-06-30"},{"cvss_score":5.9,"headline":"Mercurial Improper Certificate Validation vulnerability","id":"CVE-2010-4237","kev_date_added":null,"published":"2019-10-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":null,"url":"https://insights.sbomify.com/CVE-2018-13347/"}
