Title: Pragma FortressSSH SSH_MSG_KEXINIT Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
FortressSSH is an SSH server for Microsoft Windows platforms.
A remote buffer-overflow vulnerability exists in FortressSSH.
The source of the vulnerability is insufficient bounds-checking of data supplied in 'SSH_MSG_KEXINIT' messages by a client. The issue arises when the server logs a malicious message.
This vulnerability may permit remote code execution in vulnerable servers and may lead to a remote compromise. Presumably, a successful attack may result in a complete compromise resulting in SYSTEM access.
