CVE-2017-9108

Priority
Description
An issue was discovered in adns before 1.5.2. adnshost mishandles a missing
final newline on a stdin read. It is wrong to increment used as well as
setting r, since used is incremented according to r, later. Rather one
should be doing what read() would have done. Without this fix, adnshost may
read and process one byte beyond the buffer, perhaps crashing or perhaps
somehow leaking the value of that byte.
