A heap use-after-free flaw was found in curl versions from 7.59.0 through
7.61.1 in the code related to closing an easy handle. When closing and
cleaning up an ‘easy’ handle in the Curl_close() function, the library
code first frees a struct (without nulling the pointer) and might then
subsequently erroneously write to a struct field within that already freed
struct.
