CVE-2026-42445 Details
Description
NanaZip is an open source file archive. From 5.0.1252.0 to before 6.0.1698.0, an uncontrolled recursion vulnerability exists in the UFS/UFS2 filesystem image parser in NanaZip. The function GetAllPaths recurses into subdirectories without any depth limit or visited-inode tracking. A crafted UFS image with a deep directory tree or an inode cycle causes stack exhaustion, crashing the NanaZip process. This vulnerability is fixed in 6.0.1698.0.
A denial-of-service vulnerability has been identified in NanaZip versions 5.0.1250.0 prior to 6.0.1698.0. The issue arises from uncontrolled recursion in the UFS/UFS2 filesystem image parser, specifically in the 'GetAllPaths' function. This function recursively traverses subdirectories without a depth limit or tracking of visited inodes. As a result, a specially crafted UFS image with a deep directory structure or an inode cycle can lead to stack exhaustion, causing the NanaZip process to crash.
Users can upgrade to NanaZip version 6.0.1698.0 or later, where this vulnerability has been fixed.
