{"id":"DEBIAN-CVE-2026-115906","details":"zip is a zip library for Rust that supports reading and writing simple ZIP files. From 0.6.0 until 9.0.0, the AES entry reader in src/aes.rs verifies its HMAC only when the attacker-controlled data counter reaches zero. If the underlying bounded reader reaches the real end of the archive while data_remaining is still positive, or if an encrypted entry has no payload, the reader can return a clean end of stream without reading and comparing the authentication tag. Applications using by_index_decrypt, by_name_decrypt, by_path_decrypt, or password-enabled by_index_with_options can therefore accept modified plaintext without an authentication error. This issue is fixed in version 9.0.0.","modified":"2026-10-27T05:00:06.266199063Z","published":"2026-10-26T17:17:17.993Z","upstream":["CVE-2026-115906"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-115906"}],"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-2026-115906.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-2026-115906.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-2026-115906.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
