Error description

  • In environments with services that have path to binary
    (including arguments) longer than 260 characters, memory
    corruption occurs during install, causing unpredictable
    behaviour.
    Since a loop counter is likely to be overwritten (since both the
    string buffer that gets overflown and loop counter are both on
    stack), we are likely to iterate way farther than we initially
    intend to, resulting in Access Violation (SEGFAULT equivalent).
    
    This is caused by using strcpy instead of ossStrNCopy in
    TaskStartAutomaticDB2Services::CheckForAutoDB2ServiceAndStart
    
    The fix to this changes strcpy to ossStrNCopy.
    An additional check for null pointer will also be added to
    TaskStartAutomaticDB2Services::CheckForAutoDB2ServiceAndStart
