CVE-2025-52991 (opens in a new tab)How to fix?
There is no fixed version for Debian:unstable guix.
NVD Description
Note: Versions mentioned in the description apply only to the upstream guix package and not the guix package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
