CVE-2024-52867
guix-daemon in GNU Guix before 5ab3c4c allows privilege escalation because build outputs are accessible by local users before file metadata concerns (e.g., for setuid and setgid programs) are properly addressed.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
