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.



For Debian 8 jessie, these problems have been fixed in version 1:4.2+20130409-2+deb8u2.

We recommend that you upgrade your squashfs-tools packages.
