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-2025-64506 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-2025-64506/ (Markdown: https://insights.sbomify.com/CVE-2025-64506/index.md)","id":"CVE-2025-64506","markdown":"https://insights.sbomify.com/CVE-2025-64506/index.md","name":"CVE-2025-64506","record":{"aliases":["ALPINE-CVE-2025-64506","AZL-70841","AZL-70856","AZL-70871","AZL-70886","AZL-70897","AZL-70903","AZL-70915","AZL-70931","AZL-70975","BELL-CVE-2025-64506","CLSA-2026-1785774324","CLSA-2026-1785775169","DEBIAN-CVE-2025-64506","ECHO-db6d-1c5e-5e4d","GHSA-qpr4-xm66-hww6","JLSEC-2025-329","MINI-9h67-8994-rpw6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"libpng image library","requires_auth":"none","summary":"A heap buffer over-read in libpng allows attackers to cause denial of service or disclose memory contents when processing specific 8-bit images.","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. From version 1.6.0 to before 1.6.51, a heap buffer over-read vulnerability exists in libpng's png_write_image_8bit function when processing 8-bit images through the simplified write API with convert_to_8bit enabled. The vulnerability affects 8-bit grayscale+alpha, RGB/RGBA, and images with incomplete row data. A conditional guard incorrectly allows 8-bit input to enter code expecting 16-bit input, causing reads up to 2 bytes beyond allocated buffer boundaries. This issue has been patched in version 1.6.51.","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":"LIBPNG is vulnerable to a heap buffer over-read in `png_write_image_8bit` with grayscale+alpha or RGB/RGBA images","id":"CVE-2025-64506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libpng:libpng","products":["libpng:libpng"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Incus vulnerable to local privilege escalation through custom storage volumes","id":"CVE-2025-64507"},"packages":[],"prev":{"headline":"LIBPNG is vulnerable to a heap buffer overflow in `png_do_quantize` via malformed palette index","id":"CVE-2025-64505"},"products":["libpng"],"published":"2025-11-24","related":[{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2017-12652","kev_date_added":null,"published":"2019-07-10"},{"cvss_score":8.8,"headline":"Out-of-bounds write in libpng","id":"CVE-2018-14550","kev_date_added":null,"published":"2019-07-10"},{"cvss_score":8.3,"headline":"LIBPNG has a heap buffer overflow in png_set_quantize","id":"CVE-2026-25646","kev_date_added":null,"published":"2026-02-10"},{"cvss_score":7.6,"headline":"LIBPNG has ARM NEON Palette Expansion Out-of-Bounds Read on AArch64","id":"CVE-2026-33636","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":7.5,"headline":"LIBPNG has use-after-free via pointer aliasing in `png_set_tRNS` and `png_set_PLTE`","id":"CVE-2026-33416","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2016-10087","kev_date_added":null,"published":"2017-01-30"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2011-3464","kev_date_added":null,"published":"2012-07-22"}],"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":"partial"},"state":"PUBLISHED","updated":"2025-11-25","vendors":["pnggroup"]},"summary":"A heap buffer over-read in libpng allows attackers to cause denial of service or disclose memory contents when processing specific 8-bit images.","url":"https://insights.sbomify.com/CVE-2025-64506/"}
