ArGoSoft FTP Server any version

Multiple buffer overflows in ArGoSoft FTP Server before 1.4.1.6 allow remote authenticated users to cause a denial of service and possibly execute arbitrary code via (1) a SITE ZIP command with a long first or second argument, or (2) a SITE COPY with a long argument.

Unspecified vulnerability in ArGoSoft FTP server before 1.4.2.2 allows attackers to upload .lnk files via unknown vectors.

ArGoSoft FTP 1.4.2.4 and earlier does not limit the number of times that a bad password can be entered, which makes it easier for remote attackers to guess passwords via a brute force attack.

ArGoSoft FTP Server before 1.4.1.6 allows remote authenticated users to cause a denial of service (crash) via a SITE PASS command with a long password parameter, which causes the database to be corrupted.

Directory traversal vulnerability in ArGoSoft FTP Server before 1.4.1.6 allows remote authenticated users to determine the existence of arbitrary files via ".." sequences in the SITE UNZIP argument.

ArGoSoft FTP before 1.4.2.1 generates an error message if the user name does not exist instead of prompting for a password, which allows remote attackers to determine valid usernames.
