Description


Protek Research Lab's has discovered a vulnerability in multiple Attachmate Reflection products, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the Reflection FTP client in rftpcom.dll when processing filenames within a directory listing. This can be exploited to cause a stack-based buffer overflow via a specially crafted FTP LIST command response.

Successful exploitation allows execution of arbitrary code, but requires tricking a user into connecting to a malicious server.

The vulnerability is confirmed in version 7.2.0.106 (Reflection FTP Client version 14.1.70). Other versions may also be affected.


Solution:
Update to a fixed version (please see the vendor's advisories for details).
