Synopsis

Description

The WinSCP program installed on the remote host is version 4.x later than 4.3.7, 5.x later than 5.0.6 and prior to 5.5.3. It is, therefore, affected by the following vulnerabilities :

- An out-of-bounds read error, known as the 'Heartbleed Bug', exists related to handling TLS heartbeat extensions that allow an attacker to obtain sensitive information such as primary key material, secondary key material, and other protected content. (CVE-2014-0160)

- An error exists related to X.509 certificates, FTP with TLS, and host validation that allows an attacker to spoof a server and obtain sensitive information.
(CVE-2014-2735)
