Squashfs-Tools is an open source package. version 4.5 of Squashfs-Tools contains a security vulnerability that stems from the squashfs_opendir function in unsquash-1.c in the software that is responsible for storing the filenames in directory entries, which is then used by unsquashfs to create new files during unsquash during unsquash to create new files. The function filename operation does not validate for traversals outside the target directory, and an attacker could exploit the vulnerability to allow filenames to be written to locations outside the target directory.
