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.

Unspecified vulnerability in VanDyke VShell 3.0.1 allows remote attackers to cause a denial of service via unspecified vectors. NOTE: this information is based upon a vague advisory by a vulnerability information sales organization that does not coordinate with vendors or release actionable advisories. A CVE has been assigned for tracking purposes, but duplicates with other CVEs are difficult to determine.

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.

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.

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 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.

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.
