Description:
Luca Ercoli has discovered a vulnerability in Crystal FTP, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the handling of file extensions in response to "LIST" requests. This can be exploited to cause a buffer overflow by e.g. tricking a user into connecting to a malicious FTP server.
Successful exploitation may allow execution of arbitrary code.
The vulnerability has been confirmed on version 2.8. Other versions may also be affected.
Solution:
Do not connect to untrusted FTP servers.
Use another product.
