{"id":"ALPINE-CVE-2026-15370","details":"A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or possible code execution on the server.","modified":"2026-11-03T06:33:01.455070718Z","published":"2026-07-21T09:16:53.683Z","upstream":["CVE-2026-15370"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-15370"}],"affected":[{"package":{"name":"libssh","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/libssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.11.0"},{"fixed":"0.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-15370.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
