Description

VanDyke SecureCRT contains a remote overflow that may allow an attacker to execute arbitrary code. The issue is due to the SSH1 server not properly sanitizing the version string sent by the remote client. If a client sends a specially crafted version string, they may be able to overflow the buffer and execute arbitrary code with the same privileges as the server runs under.
