Description:
Two vulnerabilities have been reported in SmartFTP, which potentially can be exploited by malicious people to compromise a user's system.
1) A boundary error when handling "PWD" replies can be exploited to cause a buffer overflow, which potentially may allow execution of arbitrary code on a user's system.
2) A boundary error when handling file lists (eg. returned by a "LIST" command) can be exploited to cause a heap overflow by returning a file list containing an overly long, specially crafted string. This could potentially be exploited to execute arbitrary code on a user's system.
However, in order to successfully exploit the vulnerabilities, a user has to be tricked into logging in on a malicious FTP server.
Solution:
Update to SmartFTP 1.0.976 or later:
