{"id":"UBUNTU-CVE-2026-111141","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":"2026-10-17T12:58:04.192695011Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111141"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111141"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111141"},{"type":"REPORT","url":"https://github.com/gdraheim/zziplib"},{"type":"REPORT","url":"https://github.com/gdraheim/zziplib/blob/f58313c1f65f46bf73f3526d1afd4d6bb46cc4ae/zzip/zip.c#L530-L558"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/zziplib-zip-central-directory-oob-read"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/zziplib-through-0.13.80-out-of-bounds-read-via-zzip-parse-root-directory-zip64-parsing"}],"affected":[{"package":{"name":"zziplib","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.62-3","0.13.62-3ubuntu0.16.04.1","0.13.62-3ubuntu0.16.04.2","0.13.62-3ubuntu0.16.04.2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libzzip-0-13","binary_version":"0.13.62-3ubuntu0.16.04.2+esm1"},{"binary_name":"zziplib-bin","binary_version":"0.13.62-3ubuntu0.16.04.2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}},{"package":{"name":"zziplib","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.62-3.1","0.13.62-3.1ubuntu0.18.04.1","0.13.62-3.1ubuntu0.18.04.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.13.62-3.1ubuntu0.18.04.1+esm1","binary_name":"libzzip-0-13"},{"binary_name":"zziplib-bin","binary_version":"0.13.62-3.1ubuntu0.18.04.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}},{"package":{"name":"zziplib","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.62-3.2","0.13.62-3.2ubuntu1","0.13.62-3.2ubuntu1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.13.62-3.2ubuntu1.1","binary_name":"libzzip-0-13"},{"binary_version":"0.13.62-3.2ubuntu1.1","binary_name":"zziplib-bin"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}},{"package":{"name":"zziplib","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.72+dfsg.1-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.13.72+dfsg.1-1.1","binary_name":"libzzip-0-13"},{"binary_name":"zziplib-bin","binary_version":"0.13.72+dfsg.1-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}},{"package":{"name":"zziplib","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.72+dfsg.1-1.1","0.13.72+dfsg.1-1.2","0.13.72+dfsg.1-1.2build1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.13.72+dfsg.1-1.2build1","binary_name":"libzzip-0-13t64"},{"binary_name":"zziplib-bin","binary_version":"0.13.72+dfsg.1-1.2build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}},{"package":{"name":"zziplib","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.78+dfsg.1-0.2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.13.78+dfsg.1-0.2","binary_name":"libzzip-0-13t64"},{"binary_name":"zziplib-bin","binary_version":"0.13.78+dfsg.1-0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}},{"package":{"name":"zziplib","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/zziplib?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.78+dfsg.1-0.1","0.13.78+dfsg.1-0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libzzip-0-13t64","binary_version":"0.13.78+dfsg.1-0.2"},{"binary_name":"zziplib-bin","binary_version":"0.13.78+dfsg.1-0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111141.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"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"},{"type":"Ubuntu","score":"medium"}]}
