    Debian Bug     : 975365
    
    The wcsnrtombs function in all musl libc versions up through 1.2.1
    has been found to have multiple bugs in handling of destination
    buffer size when limiting the input character count, which can
    lead to infinite loop with no forward progress (no overflow) or
    writing past the end of the destination buffers.
    
    For Debian 9 stretch, this problem has been fixed in version
    1.1.16-3+deb9u1.
    
    We recommend that you upgrade your musl packages.
    
    For the detailed security status of musl please refer to
