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-2024-56737 in the wild and no public exploit code.\n\nAffected product: GNU GRUB2. 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-2024-56737/ (Markdown: https://insights.sbomify.com/CVE-2024-56737/index.md)","id":"CVE-2024-56737","markdown":"https://insights.sbomify.com/CVE-2024-56737/index.md","name":"CVE-2024-56737","record":{"aliases":["AZL-54683","AZL-54712","BELL-CVE-2024-56737","DEBIAN-CVE-2024-56737","GHSA-9vr3-263w-c6mj","UBUNTU-CVE-2024-56737"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU GRUB bootloader","requires_auth":"none","summary":"A heap-based buffer overflow in GNU GRUB allows attackers to execute arbitrary code or escalate privileges via a crafted HFS filesystem.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"grub2","vendor":"gnu"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"GNU GRUB (aka GRUB2) through 2.12 has a heap-based buffer overflow in fs/hfs.c via crafted sblock data in an HFS filesystem.","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 GRUB2","id":"CVE-2024-56737","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in GRUB2","id":"CVE-2024-56738"},"packages":[],"prev":{"headline":"Apache HertzBeat: Server-Side Request Forgery (SSRF) in Api Config Oss","id":"CVE-2024-56736"},"products":["GRUB2"],"published":"2024-12-29","related":[{"cvss_score":8.1,"headline":"Integer underflow in grub_net_recv_ip4_packets","id":"CVE-2022-28733","kev_date_added":null,"published":"2023-07-20"},{"cvss_score":8.1,"headline":"Out-of-bounds write when handling split HTTP headers","id":"CVE-2022-28734","kev_date_added":null,"published":"2023-07-20"},{"cvss_score":7.8,"headline":"Grub2: missing unregister call for gettext command may lead to use-after-free","id":"CVE-2025-61662","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":7.8,"headline":"Grub2: fs/hfs: strcpy() using the volume name (fs/hfs.c:382)","id":"CVE-2024-45782","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":7.8,"headline":"Grub2: squash4: integer overflow may lead to heap based out-of-bounds write when reading data","id":"CVE-2025-0678","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":7.8,"headline":"Grub2: udf: heap based buffer overflow in grub_udf_read_block() may lead to arbitrary code execution","id":"CVE-2025-0689","kev_date_added":null,"published":"2025-03-03"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-12-31","vendors":["GNU"]},"summary":"A heap-based buffer overflow in GNU GRUB allows attackers to execute arbitrary code or escalate privileges via a crafted HFS filesystem.","url":"https://insights.sbomify.com/CVE-2024-56737/"}
