It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-64505 in the wild and no public exploit code.\n\nAffected product: Libpng Libpng. 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-2025-64505/ (Markdown: https://insights.sbomify.com/CVE-2025-64505/index.md)","id":"CVE-2025-64505","markdown":"https://insights.sbomify.com/CVE-2025-64505/index.md","name":"CVE-2025-64505","record":{"aliases":["A-463980379","ALPINE-CVE-2025-64505","ASB-A-463980379","AZL-70763","AZL-70844","AZL-70859","AZL-70862","AZL-70865","AZL-70880","AZL-70894","AZL-70906","AZL-70909","AZL-70918","AZL-70969","BELL-CVE-2025-64505","CLSA-2025-1765288864","CLSA-2025-1765380269","CLSA-2025-1766135952","CLSA-2025-1766165929","CLSA-2026-1785493623","CLSA-2026-1785495654","DEBIAN-CVE-2025-64505","ECHO-1949-597a-9e78","GHSA-4952-h5wq-4m42","JLSEC-2025-328","MINI-5rgh-w6qx-pxvv","SUSE-SU-2025:4383-1","SUSE-SU-2025:4432-1","SUSE-SU-2026:0898-1","openSUSE-SU-2025:15797-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PNG image library","requires_auth":"none","summary":"An attacker can cause a heap buffer over-read in libpng by providing a malformed PNG file with invalid palette indices, potentially leading to crashes or code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"libpng","vendor":"libpng"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to version 1.6.51, a heap buffer over-read vulnerability exists in libpng's png_do_quantize function when processing PNG files with malformed palette indices. The vulnerability occurs when palette_lookup array bounds are not validated against externally-supplied image data, allowing an attacker to craft a PNG file with out-of-range palette indices that trigger out-of-bounds memory access.
