{"id":"UBUNTU-CVE-2026-115909","details":"zip is a zip library for Rust that supports reading and writing simple ZIP files. From 1.3.0 until 9.0.0, ZipArchive::extract in src/read/mod.rs calls Vec::with_capacity for a symbolic link target using the attacker-controlled ZIP64 uncompressed_size before reading entry data. A small archive can request an impossible capacity, causing the infallible allocation path to abort the process before the entry is validated. The failure cannot be contained with catch_unwind or a worker thread, allowing repeated denial of service in archive-processing applications. This issue is fixed in version 9.0.0.","modified":"2026-10-28T20:17:21.242327334Z","published":"2026-10-26T17:17:00Z","upstream":["CVE-2026-115909"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-115909"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-115909"},{"type":"REPORT","url":"https://github.com/zip-rs/zip2/commit/a543a1fc8f3f3eef36f27bb137230295284cdb98"},{"type":"REPORT","url":"https://github.com/zip-rs/zip2/pull/984"},{"type":"REPORT","url":"https://github.com/zip-rs/zip2/security/advisories/ghsa-q7v9-x93c-xqv3"},{"type":"REPORT","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1152227"},{"type":"REPORT","url":"https://security-tracker.debian.org/tracker/cve-2026-115909"},{"type":"REPORT","url":"https://github.com/cveproject/cvelistv5/tree/main/cves/2026/115xxx/cve-2026-115909.json"},{"type":"REPORT","url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0"},{"type":"REPORT","url":"https://nvd.nist.gov/vuln/detail/cve-2026-115909"}],"affected":[{"package":{"name":"rust-zip","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rust-zip?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.0-1","0.5.3-1","0.5.3-2"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-zip+bzip2-dev","binary_version":"0.5.3-2"},{"binary_name":"librust-zip+default-dev","binary_version":"0.5.3-2"},{"binary_version":"0.5.3-2","binary_name":"librust-zip+deflate-dev"},{"binary_version":"0.5.3-2","binary_name":"librust-zip+deflate-miniz-dev"},{"binary_version":"0.5.3-2","binary_name":"librust-zip+deflate-zlib-dev"},{"binary_name":"librust-zip+flate2-dev","binary_version":"0.5.3-2"},{"binary_name":"librust-zip+time-dev","binary_version":"0.5.3-2"},{"binary_name":"librust-zip-dev","binary_version":"0.5.3-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115909.json"}},{"package":{"name":"rust-zip","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rust-zip?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.8-2","0.5.13-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.5.13-1","binary_name":"librust-zip+bzip2-dev"},{"binary_name":"librust-zip+default-dev","binary_version":"0.5.13-1"},{"binary_version":"0.5.13-1","binary_name":"librust-zip+deflate-dev"},{"binary_version":"0.5.13-1","binary_name":"librust-zip+deflate-miniz-dev"},{"binary_version":"0.5.13-1","binary_name":"librust-zip+deflate-zlib-dev"},{"binary_name":"librust-zip+flate2-dev","binary_version":"0.5.13-1"},{"binary_name":"librust-zip+time-dev","binary_version":"0.5.13-1"},{"binary_version":"0.5.13-1","binary_name":"librust-zip-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115909.json"}},{"package":{"name":"rust-zip","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-zip?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.6-1","0.6.6-2"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-zip-dev","binary_version":"0.6.6-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115909.json"}},{"package":{"name":"rust-zip","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/rust-zip?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.1.1-3","5.1.1+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.1.1+dfsg-1","binary_name":"librust-zip-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115909.json"}},{"package":{"name":"rust-zip","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rust-zip?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.0-1","5.1.1-2","5.1.1-3"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-zip-dev","binary_version":"5.1.1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115909.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
