  script_tag(name:"insight", value:"Multiple flaws are due to:

  - An integer overflow error in 'DataSize+CurChannel' which results in a negative
    value of the 'DestPos' variable allowing to write out of bounds when setting
    Mem[DestPos].

  - An error in the size of the stack guard page on Linux, specifically a 4k stack
    guard page which is not sufficiently large and can be 'jumped' over (the stack
    guard page is bypassed).

  - An error in the glibc which allows specially crafted 'LD_LIBRARY_PATH' values
    to manipulate the heap/stack, causing them to alias.

  - An input validation (embedded newlines) error in the 'get_process_ttyname'
    function.");
