It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-8534 exists.\n\nAffected product: Libtiff Libtiff. 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-2025-8534/ (Markdown: https://insights.sbomify.com/CVE-2025-8534/index.md)","id":"CVE-2025-8534","markdown":"https://insights.sbomify.com/CVE-2025-8534/index.md","name":"CVE-2025-8534","record":{"aliases":["AZL-66078","AZL-66095","BELL-CVE-2025-8534","DEBIAN-CVE-2025-8534","ECHO-eac8-8550-89f3","GHSA-xgh3-993q-r2x8","JLSEC-2025-320","OESA-2025-2049","OESA-2025-2050","OESA-2025-2051","OESA-2025-2052","UBUNTU-CVE-2025-8534"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"libtiff image library","requires_auth":"low_privilege","summary":"A local attacker can cause a denial of service via null pointer dereference in libtiff's tiff2ps tool when specific options are enabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"libtiff","vendor":"libtiff"}],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"A vulnerability classified as problematic was found in libtiff 4.6.0. This vulnerability affects the function PS_Lvl2page of the file tools/tiff2ps.c of the component tiff2ps. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The name of the patch is 6ba36f159fd396ad11bf6b7874554197736ecc8b. It is recommended to apply a patch to fix this issue.
