FTP-KRB double free

libcurl can be told to use kerberos over FTP to a server, as set with the CURLOPTKRBLEVEL option. During such kerberos FTP data transfer, the server sends data to curl in blocks with the 32-bit size of each block first and then that amount of data immediately following. A malicious or broken serv...

curl: krb5: double-free in read_data() after realloc() fail

Summary: In 'lib/security.c', there is a double-free of the reference 'buf-data' on the teardown path if 'Curlsaferealloc' fails. Also, since we read 'len' from the 'fd', the sender might be able to remotely trigger a realloc failure, and then the double-free, by sending the value 0x7fffffff...
