{"id":"CVE-2026-111141","summary":"zziplib through 0.13.80 Out-of-Bounds Read via __zzip_parse_root_directory ZIP64 Parsing","details":"zziplib through 0.13.80 contains an out-of-bounds read vulnerability in __zzip_parse_root_directory() in zzip/zip.c that allows attackers to read past the mapped central directory in mmap builds due to an ineffective bounds check. Attackers can supply a crafted ZIP whose entry name ends at the central directory end, triggering 28-byte ZIP64 extra field over-reads via zzip_dir_open() that crash the process.","modified":"2026-10-16T10:46:27.758832741Z","published":"2026-10-15T18:57:33.318Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111141.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111141.json"},{"type":"PACKAGE","url":"https://github.com/gdraheim/zziplib"},{"type":"ARTICLE","url":"https://github.com/gdraheim/zziplib/blob/f58313c1f65f46bf73f3526d1afd4d6bb46cc4ae/zzip/zip.c#L530-L558"},{"type":"ARTICLE","url":"https://hackmd.io/@haind-pwn/zziplib-zip-central-directory-oob-read"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111141"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/zziplib-through-0.13.80-out-of-bounds-read-via-zzip-parse-root-directory-zip64-parsing"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gdraheim/zziplib","events":[{"introduced":"0"},{"last_affected":"f58313c1f65f46bf73f3526d1afd4d6bb46cc4ae"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.13.80"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.13.80","v0.13.79","v0.13.78","v0.13.77","v0.13.76","v0.13.75","v0.13.74","v0.13.73","v0.13.72","v0.13.69","v0.13.68","v0.13.67","v0.13.66","v0.13.65","v0.13.64","v0.13.63","v0.13.62","v0.13.61","v0.13.60","v0.13.59","v0.13.58","v0.13.57","v0.13.56","v0.13.55","v0.13.54","v0.13.52","v0.13.51","v0.13.50","v0.13.48","v0.13.36"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111141.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
