CVE-2026-42445

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.

Summary		(es) NanaZip es un archivador de archivos de código abierto. Desde la 5.0.1252.0 hasta antes de la 6.0.1698.0, existe una vulnerabilidad de recursión incontrolada en el analizador de imágenes de sistemas de archivos UFS/UFS2 en NanaZip. La función GetAllPaths recurre en subdirectorios sin ningún límite de profundidad ni seguimiento de inodos visitados. Una imagen UFS manipulada con un árbol de directorios profundo o un ciclo de inodos causa el agotamiento de la pila, provocando el bloqueo del proceso de NanaZip. Esta vulnerabilidad está corregida en la 6.0.1698.0.
