SSH: SecureCRT Client Buffer Overflow
This signature detects a malicious SSH server attempting to overflow the buffer of a SecureCRT SSH client. If succesful, the client would make a subsequent connection to the SSH server host, giving full shell access.
Extended Description
The SecureCRT client is prone to a buffer-overflow condition when attempting to handle an overly long SSH1 protocol identifier string. Reportedly, an attacker can exploit this issue via a malicious server. Exploiting this issue may allow an attacker to execute arbitrary code or may cause the client to crash.
