Medium severity, CVSS 6.2. EPSS: 0.3% chance of exploitation in the next 30 days.

fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories.

• Netbsd Netbsd: version 1.5 only; version 1.5.1 only
• OpenBSD OpenBSD: up to and including 2.9
