Summary
gdu fails to strip terminal escape sequences from directory and file names when printing paths after TUI exit. Attackers can craft malicious directory or file names containing escape sequences that are interpreted by the terminal, enabling title spoofing, clipboard manipulation, or other terminal-dependent effects.
A flaw was found in gdu, a disk usage analyzer. Red Hat products are not affected by this vulnerability as gdu is not shipped in any Red Hat product.
Community packages in Fedora and EPEL are affected. Red Hat severity: Moderate — CVSS 5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).
Weakness: CWE-838.

Mitigation checklist
- Avoid running gdu in directories where untrusted users can create files or subdirectories with crafted names. Pipe gdu output through a terminal escape filter to neutralize injected sequences.
