Format string vulnerability in VShell SSH gateway 1.0.1 and earlier allows remote attackers to execute arbitrary commands via a user name that contains format string specifiers.

VShell SSH gateway 1.0.1 and earlier has a default port forwarding rule of 0.0.0.0/0.0.0.0, which could allow local users to conduct arbitrary port forwarding to other systems.

Buffer overflow in VanDyke SecureCRT before 3.4.2, when using the SSH-1 protocol, allows remote attackers to execute arbitrary code via a long (1) username or (2) password.

Buffer overflow in Van Dyke SecureCRT SSH client before 3.4.6, and 4.x before 4.0 beta 3, allows an SSH server to execute arbitrary code via a long SSH1 protocol version string.

SSH2 clients for VanDyke (1) SecureCRT 4.0.2 and 3.4.7, (2) SecureFX 2.1.2 and 2.0.4, and (3) Entunnel 1.0.2 and earlier, do not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials.

SecureCRT 4.0, 4.1, and possibly other versions, allows remote attackers to execute arbitrary commands via a telnet:// URL that uses the /F option to specify a configuration file on a samba share.

Buffer overflow in SecureCRT 5.0.4 and earlier and SecureFX 3.0.4 and earlier allows remote attackers to have an unknown impact when a Unicode string is converted to a "narrow" string.
