SecureCRT is vulnerable to buffer overflow from improper handling of long password input.
SecureCRT is a terminal emulator and SSH client for Windows. If the SSH1 protocol is used and the user enters a password 300 characters or more in length, SecureCRT will crash, with the following error displayed by Windows:
"SECURECRT caused an invalid page fault in module MSVCRT.DLL..."
Local users may be able to execute arbitrary code on the client host by supplying a long password to SecureCRT.
The CERT/CC is currently unaware of a practical solution to this problem.
Thanks to Blackshell Security Advisory for reporting this vulnerability.
