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-2015-7506 in the wild and no public exploit code.\n\nAffected product: Libnsgif. 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-2015-7506/ (Markdown: https://insights.sbomify.com/CVE-2015-7506/index.md)","id":"CVE-2015-7506","markdown":"https://insights.sbomify.com/CVE-2015-7506/index.md","name":"CVE-2015-7506","record":{"aliases":["DEBIAN-CVE-2015-7506","GHSA-pq64-838x-3vmj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GIF image library","requires_auth":"none","summary":"Attackers can cause a denial of service via a crafted GIF file due to an out-of-bounds read in the Libnsgif library.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libnsgif","vendor":"netsurf-browser"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"The gif_next_LZW function in libnsgif.c in Libnsgif 0.1.2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted LZW stream in a GIF 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":"Denial of service in Libnsgif","id":"CVE-2015-7506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2015"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Libnsbmp","id":"CVE-2015-7507"},"packages":[],"prev":{"headline":"Memory corruption in Libnsgif","id":"CVE-2015-7505"},"products":["Libnsgif"],"published":"2020-02-18","related":[{"cvss_score":8.8,"headline":"Memory corruption in Libnsgif","id":"CVE-2015-7505","kev_date_added":null,"published":"2020-02-18"}],"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":"2024-08-06","vendors":["Libnsgif"]},"summary":"Attackers can cause a denial of service via a crafted GIF file due to an out-of-bounds read in the Libnsgif library.","url":"https://insights.sbomify.com/CVE-2015-7506/"}
