An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2007-3645 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-2007-3645/ (Markdown: https://insights.sbomify.com/CVE-2007-3645/index.md)","id":"CVE-2007-3645","markdown":"https://insights.sbomify.com/CVE-2007-3645/index.md","name":"CVE-2007-3645","record":{"aliases":["DEBIAN-CVE-2007-3645","GHSA-wc53-cvcx-2wqx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libarchive library","requires_auth":"none","summary":"A NULL pointer dereference in libarchive allows remote attackers to cause a denial of service via crafted PAX or TAR archives.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"libarchive","vendor":"freebsd"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"archive_read_support_format_tar.c in libarchive before 2.2.4 allows user-assisted remote attackers to cause a denial of service (crash) via (1) an end-of-file condition within a tar header that follows a pax extension header or (2) a malformed pax extension header in an (a) PAX or a (b) TAR archive, which results in a NULL pointer dereference, a different issue than CVE-2007-3644.","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":"Null dereference in n/a","id":"CVE-2007-3645","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2007"},"n_packages":0,"n_references":17,"next":{"headline":"SQL injection in n/a","id":"CVE-2007-3646"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2007-3644"},"products":["n/a"],"published":"2007-07-15","related":[{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2007-3641","kev_date_added":null,"published":"2007-07-14"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2010-4666","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":7.5,"headline":"Use after free in n/a","id":"CVE-2011-1779","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2011-1777","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2011-1778","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":4.3,"headline":"Denial of service in n/a","id":"CVE-2007-3644","kev_date_added":null,"published":"2007-07-14"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"A NULL pointer dereference in libarchive allows remote attackers to cause a denial of service via crafted PAX or TAR archives.","url":"https://insights.sbomify.com/CVE-2007-3645/"}
