Richard Weinberger reported that unsquashfs in squashfs-tools, the tools to create and extract Squashfs filesystems, does not check for duplicate filenames within a directory. An attacker can take advantage of this flaw for writing to arbitrary files to the filesystem if a malformed Squashfs image is processed.
