{"id":"DEBIAN-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":"2026-10-27T05:00:07.430496141Z","published":"2026-10-26T17:17:18.450Z","upstream":["CVE-2026-115909"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-115909"}],"affected":[{"package":{"name":"rust-zip","ecosystem":"Debian:12","purl":"pkg:deb/debian/rust-zip?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.3-3","0.6.6-1","0.6.6-2","0.6.6-3","0.6.6-4","0.6.6-5","2.5.0-1","5.1.1+dfsg-1","5.1.1-1","5.1.1-2","5.1.1-3","5.1.1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115909.json"}},{"package":{"name":"rust-zip","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-zip?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.0-1","5.1.1+dfsg-1","5.1.1-1","5.1.1-2","5.1.1-3","5.1.1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115909.json"}},{"package":{"name":"rust-zip","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-zip?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.0-1","5.1.1+dfsg-1","5.1.1-1","5.1.1-2","5.1.1-3","5.1.1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-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"}]}
