CVE-2001-1470
First published: Thu Jan 18 2001(Updated: )
The IDEA cipher as implemented by SSH1 does not protect the final block of a message against modification, which allows remote attackers to modify the block without detection by changing its cyclic redundancy check (CRC) to match the modifications to the message.
