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-2015-8931 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2015-8931/ (Markdown: https://insights.sbomify.com/CVE-2015-8931/index.md)","id":"CVE-2015-8931","markdown":"https://insights.sbomify.com/CVE-2015-8931/index.md","name":"CVE-2015-8931","record":{"aliases":["DEBIAN-CVE-2015-8931","GHSA-ghcq-m3mh-5p57","UBUNTU-CVE-2015-8931"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"libarchive library","requires_auth":"none","summary":"Integer overflows in libarchive's mtree parser allow remote attackers to cause undefined behavior, potentially leading to denial of service or code execution via crafted files.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"libarchive","vendor":"libarchive"},{"product":"linux_enterprise_desktop","vendor":"suse"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"linux_enterprise_software_development_kit","vendor":"suse"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Multiple integer overflows in the (1) get_time_t_max and (2) get_time_t_min functions in archive_read_support_format_mtree.c in libarchive before 3.2.0 allow remote attackers to have unspecified impact via a crafted mtree file, which triggers undefined behavior.","ecosystems":[],"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":"Integer overflow in n/a","id":"CVE-2015-8931","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux","libarchive:libarchive","suse:linux_enterprise_desktop","suse:linux_enterprise_server","suse:linux_enterprise_software_development_kit"],"type":"integer_overflow","year":"2015"},"n_packages":0,"n_references":12,"next":{"headline":"The compress_bidder_init function in archive_read_support_filter_compress.c in libarchive before 3.2.0 allows remote attackers to cause a de","id":"CVE-2015-8932"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2015-8930"},"products":["n/a"],"published":"2016-09-20","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Integer overflows in libarchive's mtree parser allow remote attackers to cause undefined behavior, potentially leading to denial of service or code execution via crafted files.","url":"https://insights.sbomify.com/CVE-2015-8931/"}
