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-2018-11243 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-2018-11243/ (Markdown: https://insights.sbomify.com/CVE-2018-11243/index.md)","id":"CVE-2018-11243","markdown":"https://insights.sbomify.com/CVE-2018-11243/index.md","name":"CVE-2018-11243","record":{"aliases":["DEBIAN-CVE-2018-11243","GHSA-xvcg-hv6h-729g","UBUNTU-CVE-2018-11243","openSUSE-SU-2020:0162-1","openSUSE-SU-2020:0179-1","openSUSE-SU-2024:11477-1"],"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":"Remote attackers can cause denial of service in UPX via a crafted file triggering a double free error during unpacking.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"upx","vendor":"upx"}],"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-415","name":"Double Free"}],"description":"PackLinuxElf64::unpack in p_lx_elf.cpp in UPX 3.95 allows remote attackers to cause a denial of service (double free), limit the ability of a malware scanner to operate on the entire original data, or possibly have unspecified other impact via a crafted file.","ecosystems":["SUSE:Package Hub 15 SP1","openSUSE:Leap 15.1","openSUSE:Tumbleweed"],"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":"Use after free in n/a","id":"CVE-2018-11243","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2018"},"n_packages":3,"n_references":9,"next":{"headline":"Missing authorization in n/a","id":"CVE-2018-11244"},"packages":[{"ecosystem":"SUSE:Package Hub 15 SP1","fixed":["1.03-bp151.4.3.1"],"introduced":["0"],"last_affected":[],"package":"ucl","purl":"pkg:rpm/suse/ucl\u0026distro=SUSE%20Package%20Hub%2015%20SP1","source":"openSUSE-SU-2020:0179-1"},{"ecosystem":"openSUSE:Leap 15.1","fixed":["1.03-lp151.3.3.1"],"introduced":["0"],"last_affected":[],"package":"ucl","purl":"pkg:rpm/opensuse/ucl\u0026distro=openSUSE%20Leap%2015.1","source":"openSUSE-SU-2020:0162-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.03-4.9"],"introduced":["0"],"last_affected":[],"package":"ucl","purl":"pkg:rpm/opensuse/ucl\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11477-1"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2018-11242"},"products":["n/a"],"published":"2018-05-18","related":[{"cvss_score":7.8,"headline":"Memory corruption in upx","id":"CVE-2020-27796","kev_date_added":null,"published":"2022-08-25"},{"cvss_score":7.8,"headline":"Memory corruption in upx","id":"CVE-2020-27799","kev_date_added":null,"published":"2022-08-25"},{"cvss_score":7.8,"headline":"Memory corruption in upx","id":"CVE-2020-27800","kev_date_added":null,"published":"2022-08-25"},{"cvss_score":7.8,"headline":"Memory corruption in upx","id":"CVE-2020-27801","kev_date_added":null,"published":"2022-08-25"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14296","kev_date_added":null,"published":"2019-07-27"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2017-16869","kev_date_added":null,"published":"2017-11-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"Remote attackers can cause denial of service in UPX via a crafted file triggering a double free error during unpacking.","url":"https://insights.sbomify.com/CVE-2018-11243/"}
