DESCRIPTION:
r0ut3r has discovered a vulnerability in GoodTech SSH Server, which
can be exploited by malicious users to compromise a vulnerable
system.
The vulnerability is caused due to a boundary error when processing
overly long strings passed as arguments to e.g. the SFTP "open",
"opendir", and "unlink" commands, and can be exploited to cause a
stack-based buffer overflow.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 6.4. Other versions may
