Description:
Gerry Eisenhaur has discovered a vulnerability in WeOnlyDo wodSSHServer, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the handling of the key exchange algorithm string sent by an SSH client. This can be exploited to cause a stack-based buffer overflow and may allow arbitrary code execution.
The vulnerability has been confirmed in versions 1.2.7 and 1.3.3 DEMO. Other versions may also be affected.
Solution:
Update to version 1.3.4.
