Multiple buffer overflows in SmartFTP 1.0.973, and other versions before 1.0.976, allow remote attackers to execute arbitrary code via (1) a long response to a PWD command, which triggers a stack-based overflow, and (2) a long line in a response to a file LIST command, which triggers a heap-based overflow.

Directory traversal vulnerability in SmartSoft Ltd SmartFTP Client 4.0.1124.0, and possibly other versions before 4.0 Build 1133, allows remote FTP servers to overwrite arbitrary files via a "..\" (dot dot backslash) in a filename. NOTE: some of these details are obtained from third party information.

Unspecified vulnerability in SmartFTP before 4.0 Build 1142 allows attackers to have an unknown impact via a long filename.

SmartFTP Client 10.0.2909.0 contains multiple denial of service vulnerabilities that allow attackers to crash the application through specific input manipulation. Attackers can trigger crashes by entering malformed paths, using invalid IP addresses, or clearing connection history in the client's interface.
