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-2009-2042 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-2009-2042/ (Markdown: https://insights.sbomify.com/CVE-2009-2042/index.md)","id":"CVE-2009-2042","markdown":"https://insights.sbomify.com/CVE-2009-2042/index.md","name":"CVE-2009-2042","record":{"aliases":["GHSA-rh45-m734-j52q"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"PNG image library","requires_auth":"none","summary":"Remote attackers can read sensitive memory by tricking users into opening specially crafted 1-bit interlaced PNG files with specific widths.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libpng","vendor":"libpng"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"libpng before 1.2.37 does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via \"out-of-bounds pixels\" in the file.","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":"Information disclosure in n/a","id":"CVE-2009-2042","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libpng:libpng","products":["libpng:libpng"],"type":"information_disclosure","year":"2009"},"n_packages":0,"n_references":27,"next":{"headline":"Null dereference in n/a","id":"CVE-2009-2043"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2009-2041"},"products":["n/a"],"published":"2009-06-12","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can read sensitive memory by tricking users into opening specially crafted 1-bit interlaced PNG files with specific widths.","url":"https://insights.sbomify.com/CVE-2009-2042/"}
