What is CVE-2026-42445?

NanaZip, an open source file archive tool, is susceptible to an uncontrolled recursion issue in its UFS/UFS2 filesystem image parser. Versions from 5.0.1252.0 to just before 6.0.1698.0 are affected. The vulnerability occurs when the GetAllPaths function processes subdirectories without a limit on recursion depth or adequate inode tracking. This flaw can lead to stack exhaustion, resulting in the crash of the NanaZip application when handling specially crafted UFS images containing deep directory structures or inode cycles. The issue has been resolved in version 6.0.1698.0.

Affected Version(s)

NanaZip >= 5.0.1250.0, < 6.0.1698.0
