عنوانGNU cramfs-tools below v2.2 Symlink Following
الوصفGNU cramfs-tools is a set of utilities for managing the Cramfs (Compressed ROM File System), a lightweight, read-only Linux file system optimized for space efficiency and low memory usage. It includes mkcramfs/mkfs.cramfs to create Cramfs images from directories, and cramfsck to verify integrity or extract contents. cramfs-tools cramfsck contains a hostile-prestate filesystem issue in continue-on-error mode (-c): if the chosen extraction directory already exists as a symlink, cramfsck -x records the mkdir() failure but still continues extraction and performs filesystem writes through the symlink target, outside the intended destination directory. This aligns with CWE-59: Improper Link Resolution Before File Access.
