{"id":"CVE-2023-45853","details":"MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_64 via a long filename, comment, or extra field. NOTE: MiniZip is not a supported part of the zlib product. NOTE: pyminizip through 0.2.6 is also vulnerable because it bundles an affected zlib version, and exposes the applicable MiniZip code through its compress API.","aliases":["GHSA-mq29-j5xf-cjwr","PYSEC-2026-501"],"modified":"2026-10-28T10:35:14.283472736Z","published":"2023-10-14T00:00:00Z","related":["SUSE-SU-2023:4215-1","SUSE-SU-2023:4216-1","SUSE-SU-2023:4217-1","SUSE-SU-2024:2431-1","SUSE-SU-2026:20659-1","SUSE-SU-2026:20709-1","SUSE-SU-2026:21013-1","SUSE-SU-2026:21151-1","openSUSE-SU-2024:13363-1","openSUSE-SU-2024:13462-1","openSUSE-SU-2025:14857-1","openSUSE-SU-2026:20487-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45853.json","unresolved_ranges":[{"extracted_events":[{"range":[{"last_affected":"0.2.6"}],"source":"DESCRIPTION"}]}],"cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-398330.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-470355.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-769027.html"},{"type":"WEB","url":"https://chromium.googlesource.com/chromium/src/+/d709fb23806858847131027da95ef4c548813356"},{"type":"WEB","url":"https://chromium.googlesource.com/chromium/src/+/de29dd6c7151d3cd37cb4cf0036800ddfb1d8b61"},{"type":"WEB","url":"https://github.com/madler/zlib/blob/ac8f12c97d1afd9bafa9c710f827d40a407d3266/contrib/README.contrib#L1-L4"},{"type":"WEB","url":"https://www.winimage.com/zLibDll/minizip.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45853.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45853"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202401-18"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20231130-0009/"},{"type":"FIX","url":"https://github.com/madler/zlib/pull/843"},{"type":"PACKAGE","url":"https://pypi.org/project/pyminizip/#history"},{"type":"ARTICLE","url":"http://www.openwall.com/lists/oss-security/2023/10/20/9"},{"type":"ARTICLE","url":"http://www.openwall.com/lists/oss-security/2024/01/24/10"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2023/11/msg00026.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/madler/zlib","events":[{"introduced":"0"},{"fixed":"51b7f2abdade71cd9bb0e7a373ef2610ec6f9daf"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"1.3"}],"source":"DESCRIPTION"},{"range":[{"introduced":"0"},{"fixed":"1.3.1"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:zlib:zlib:*:*:*:*:*:*:*:*"}]}}],"versions":["v1.3","v1.2.13","v1.2.12","v1.2.11","v1.2.10","v1.2.9","v1.2.8","v1.2.7.3","v1.2.7.2","v1.2.7.1","v1.2.7","v1.2.6.1","v1.2.6","v1.2.5.3","v1.2.5.2","v1.2.5.1","v1.2.5","v1.2.4.5","v1.2.4.4","v1.2.4.3","v1.2.4.2","v1.2.4.1","v1.2.4","v1.2.4-pre2","v1.2.4-pre1","v1.2.3.9","v1.2.3.8","v1.2.3.7","v1.2.3.6","v1.2.3.5","v1.2.3.4","v1.2.3.3","v1.2.3.2","v1.2.3.1","v1.2.3","v1.2.2.4","v1.2.2.3","v1.2.2.2","v1.2.2.1","v1.2.2","v1.2.1.2","v1.2.1.1","v1.2.1","v1.2.0.8","v1.2.0.7","v1.2.0.6","v1.2.0.5","v1.2.0.4","v1.2.0.3","v1.2.0.2","v1.2.0.1","v1.2.0","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.9","v1.0.8","v1.0.7","v1.0.5","v1.0.4","v1.0.2","v1.0.1","v1.0-pre","v0.99","v0.95","v0.94","v0.93","v0.92","v0.91","v0.9","v0.8","v0.79","v0.71"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-45853.json","vanir_signatures":[{"deprecated":false,"digest":{"line_hashes":["215690993403917231272694230425219987002","7019122414051018615790014750645896555","255906567231977922390158965099391548767","2979242068947975725579226479034357614","183751973083521201577729731315703301636","248844941626262695281549603824626887338","320788635962490165830021216345105451853","139412783718332547720366439434782111756"],"threshold":0.9},"id":"CVE-2023-45853-25ba5c2b","signature_type":"Line","signature_version":"v1","source":"https://github.com/madler/zlib/commit/51b7f2abdade71cd9bb0e7a373ef2610ec6f9daf","target":{"file":"contrib/infback9/inftree9.c"}},{"digest":{"line_hashes":["146082642291687623367597030759784561315","152050153557000594638610353463892202290","167871161695338292225404021815429421053","226964300907398093233119743133210393617","210714638011015966034035419241960876875","299788994572251005544425986055084261218","278248442459515735326130533085265985381","222024272414522711481295922899227189988"],"threshold":0.9},"id":"CVE-2023-45853-6a37fcaf","signature_type":"Line","signature_version":"v1","source":"https://github.com/madler/zlib/commit/51b7f2abdade71cd9bb0e7a373ef2610ec6f9daf","target":{"file":"inftrees.c"},"deprecated":false},{"signature_type":"Line","signature_version":"v1","source":"https://github.com/madler/zlib/commit/51b7f2abdade71cd9bb0e7a373ef2610ec6f9daf","target":{"file":"deflate.c"},"deprecated":false,"digest":{"line_hashes":["178093991456060150070942589027539997666","67123618263193801280741285694335332119","140132922840055513513963220051526309244"],"threshold":0.9
