{"id":"DEBIAN-CVE-2025-52991","details":"The Nix, Lix, and Guix package managers default to using temporary build directories in a world-readable and world-writable location. This allows standard users to deceive the package manager into using directories with pre-existing content, potentially leading to unauthorized actions or data manipulation. This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b.","modified":"2026-08-27T23:05:40.613031462Z","published":"2025-06-27T14:15:41.253Z","upstream":["CVE-2025-52991"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-52991"}],"affected":[{"package":{"name":"guix","ecosystem":"Debian:11","purl":"pkg:deb/debian/guix?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.0-4","1.2.0-4+deb11u1","1.2.0-4+deb11u2","1.2.0-4+deb11u3","1.3.0+26720.a2e4e-1","1.3.0+26756.c07b5-1","1.3.0+26756.c07b5-2","1.3.0-1","1.3.0-2","1.3.0-3","1.3.0-4","1.3.0-5","1.3.0~rc1-1","1.4.0+154709.ab1b557d8f3-1","1.4.0+154710+ab1b5-1","1.4.0+154710+ab1b5-2","1.4.0+154928+f1810-1","1.4.0-1","1.4.0-2","1.4.0-3","1.4.0-4","1.4.0-5","1.4.0-6","1.4.0-7","1.4.0-8","1.4.0-9","1.4.0~rc1-1","1.4.0~rc1-2","1.4.0~rc2-1"],"ecosystem_specific":{"urgency":"end-of-life"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-52991.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N"}]}
