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-2018-6542 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-2018-6542/ (Markdown: https://insights.sbomify.com/CVE-2018-6542/index.md)","id":"CVE-2018-6542","markdown":"https://insights.sbomify.com/CVE-2018-6542/index.md","name":"CVE-2018-6542","record":{"aliases":["DEBIAN-CVE-2018-6542","ECHO-46fc-3288-0ab3","GHSA-66ww-fgg3-pc35","SUSE-SU-2018:1507-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ZZIPlib compression library","requires_auth":"none","summary":"A bus error in ZZIPlib caused by misaligned memory access allows attackers to cause a denial of service via crafted disk64_trailer seek values.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zziplib","vendor":"gdraheim"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"In ZZIPlib 0.13.67, there is a bus error (when handling a disk64_trailer seek value) caused by loading of a misaligned address in the zzip_disk_findfirst function of zzip/mmapped.c.","ecosystems":["SUSE:Linux Enterprise Desktop 12 SP3","SUSE:Linux Enterprise Software Development Kit 12 SP3","SUSE:Linux Enterprise Workstation Extension 12 SP3"],"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":"Memory corruption in n/a","id":"CVE-2018-6542","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":3,"n_references":1,"next":{"headline":"Integer overflow in n/a","id":"CVE-2018-6543"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Desktop 12 SP3","fixed":["0.13.67-10.11.1"],"introduced":["0"],"last_affected":[],"package":"zziplib","purl":"pkg:rpm/suse/zziplib\u0026distro=SUSE%20Linux%20Enterprise%20Desktop%2012%20SP3","source":"SUSE-SU-2018:1507-1"},{"ecosystem":"SUSE:Linux Enterprise Software Development Kit 12 SP3","fixed":["0.13.67-10.11.1"],"introduced":["0"],"last_affected":[],"package":"zziplib","purl":"pkg:rpm/suse/zziplib\u0026distro=SUSE%20Linux%20Enterprise%20Software%20Development%20Kit%2012%20SP3","source":"SUSE-SU-2018:1507-1"},{"ecosystem":"SUSE:Linux Enterprise Workstation Extension 12 SP3","fixed":["0.13.67-10.11.1"],"introduced":["0"],"last_affected":[],"package":"zziplib","purl":"pkg:rpm/suse/zziplib\u0026distro=SUSE%20Linux%20Enterprise%20Workstation%20Extension%2012%20SP3","source":"SUSE-SU-2018:1507-1"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2018-6541"},"products":["n/a"],"published":"2018-02-02","related":[{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2024-39134","kev_date_added":null,"published":"2024-06-27"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2018-16548","kev_date_added":null,"published":"2018-09-05"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2018-7727","kev_date_added":null,"published":"2018-03-06"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2020-18770","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":5.5,"headline":"Path traversal in n/a","id":"CVE-2018-17828","kev_date_added":null,"published":"2018-10-01"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2017-5977","kev_date_added":null,"published":"2017-03-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"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":"2024-08-05","vendors":["n/a"]},"summary":"A bus error in ZZIPlib caused by misaligned memory access allows attackers to cause a denial of service via crafted disk64_trailer seek values.","url":"https://insights.sbomify.com/CVE-2018-6542/"}
