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-2015-6778 in the wild and no public exploit code.\n\nAffected product: Google Chrome. 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-2015-6778/ (Markdown: https://insights.sbomify.com/CVE-2015-6778/index.md)","id":"CVE-2015-6778","markdown":"https://insights.sbomify.com/CVE-2015-6778/index.md","name":"CVE-2015-6778","record":{"aliases":["GHSA-g2cv-288r-rh4q","UBUNTU-CVE-2015-6778"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Chrome PDFium","requires_auth":"none","summary":"Remote attackers can cause denial of service or potential code execution in Chrome via crafted JBIG2 PDF documents.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"chrome","vendor":"google"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The CJBig2_SymbolDict class in fxcodec/jbig2/JBig2_SymbolDict.cpp in PDFium, as used in Google Chrome before 47.0.2526.73, allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via a PDF document containing crafted data with JBIG2 compression.","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-2015-6778","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:chrome","products":["google:chrome"],"type":"memory_corruption","year":"2015"},"n_packages":0,"n_references":9,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2015-6779"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2015-6777"},"products":["n/a"],"published":"2015-12-06","related":[{"cvss_score":9.6,"headline":"Google Chromium GPU Heap Buffer Overflow","id":"CVE-2022-4135","kev_date_added":"2022-11-28","published":"2022-11-25"},{"cvss_score":9.6,"headline":"Google Chrome Use-After-Free","id":"CVE-2020-16017","kev_date_added":"2021-11-03","published":"2021-01-08"},{"cvss_score":9.6,"headline":"Google Chrome for Android UI Heap Buffer Overflow","id":"CVE-2020-16010","kev_date_added":"2021-11-03","published":"2020-11-03"},{"cvss_score":8.8,"headline":"Google Chromium V8 Out of Bounds Write","id":"CVE-2026-87491","kev_date_added":"2026-09-09","published":"2026-09-09"},{"cvss_score":8.8,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2026-85046","kev_date_added":"2026-09-04","published":"2026-09-03"},{"cvss_score":8.8,"headline":"Google Chromium V8 Out-of-Bounds Read and Write","id":"CVE-2026-11645","kev_date_added":"2026-06-09","published":"2026-06-08"},{"cvss_score":8.8,"headline":"Google Dawn Use-After-Free","id":"CVE-2026-5281","kev_date_added":"2026-04-01","published":"2026-04-01"}],"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":["n/a"]},"summary":"Remote attackers can cause denial of service or potential code execution in Chrome via crafted JBIG2 PDF documents.","url":"https://insights.sbomify.com/CVE-2015-6778/"}
