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-2018-8977 in the wild and no public exploit code.\n\nAffected product: Exiv2 Exiv2. 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-2018-8977/ (Markdown: https://insights.sbomify.com/CVE-2018-8977/index.md)","id":"CVE-2018-8977","markdown":"https://insights.sbomify.com/CVE-2018-8977/index.md","name":"CVE-2018-8977","record":{"aliases":["GHSA-qhcx-r24w-jj9w"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Image metadata library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via invalid memory access in Exiv2 by providing a crafted file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exiv2","vendor":"exiv2"}],"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":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"In Exiv2 0.26, the Exiv2::Internal::printCsLensFFFF function in canonmn_int.cpp allows remote attackers to cause a denial of service (invalid memory access) via a crafted 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":"Memory corruption in n/a","id":"CVE-2018-8977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"exiv2:exiv2","products":["exiv2:exiv2"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-8978"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2018-8976"},"products":["n/a"],"published":"2018-03-25","related":[{"cvss_score":8.8,"headline":"Out-of-bounds write in exiv2","id":"CVE-2023-44398","kev_date_added":null,"published":"2023-11-06"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2019-9143","kev_date_added":null,"published":"2019-02-25"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2019-9144","kev_date_added":null,"published":"2019-02-25"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2018-14046","kev_date_added":null,"published":"2018-07-13"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12955","kev_date_added":null,"published":"2017-08-18"},{"cvss_score":8.1,"headline":"Memory corruption in n/a","id":"CVE-2018-14338","kev_date_added":null,"published":"2018-07-17"},{"cvss_score":8.1,"headline":"Information disclosure in n/a","id":"CVE-2018-9305","kev_date_added":null,"published":"2018-04-04"}],"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":"Remote attackers can cause a denial of service via invalid memory access in Exiv2 by providing a crafted file.","url":"https://insights.sbomify.com/CVE-2018-8977/"}
