    squashfs: more metadata hardening · 953f918d
    Linus Torvalds authored Jul 30, 2018
    commit d5125847 upstream.
    
    Anatoly reports another squashfs fuzzing issue, where the decompression
    parameters themselves are in a compressed block.
    
    This causes squashfs_read_data() to be called in order to read the
    decompression options before the decompression stream having been set
    up, making squashfs go sideways.
