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-2019-20053 in the wild and no public exploit code.\n\nAffected product: Opensuse Backports. 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-2019-20053/ (Markdown: https://insights.sbomify.com/CVE-2019-20053/index.md)","id":"CVE-2019-20053","markdown":"https://insights.sbomify.com/CVE-2019-20053/index.md","name":"CVE-2019-20053","record":{"aliases":["DEBIAN-CVE-2019-20053","GHSA-phmx-286h-jcc3","UBUNTU-CVE-2019-20053"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UPX executable packer","requires_auth":"none","summary":"A crafted Mach-O file causes a null pointer dereference in UPX, leading to a denial of service during unpacking.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"backports","vendor":"opensuse"},{"product":"leap","vendor":"opensuse"},{"product":"upx","vendor":"upx"}],"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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"An invalid memory address dereference was discovered in the canUnpack function in p_mach.cpp in UPX 3.95 via a crafted Mach-O file.","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-2019-20053","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensuse:backports","products":["opensuse:backports","opensuse:leap"],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":3,"next":{"headline":"Null dereference in n/a","id":"CVE-2019-20054"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2019-20052"},"products":["n/a"],"published":"2019-12-27","related":[{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14524","kev_date_added":null,"published":"2019-08-02"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-10592","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":7.1,"headline":"Integer overflow in VLC","id":"CVE-2019-5459","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":5.9,"headline":"Denial of service in Shadowsocks","id":"CVE-2019-5163","kev_date_added":null,"published":"2019-12-03"},{"cvss_score":5.5,"headline":"Use after free in VLC Media Player","id":"CVE-2019-5460","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":3.5,"headline":"Denial of service in pdns","id":"CVE-2019-10163","kev_date_added":null,"published":"2019-07-30"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"A crafted Mach-O file causes a null pointer dereference in UPX, leading to a denial of service during unpacking.","url":"https://insights.sbomify.com/CVE-2019-20053/"}
