DESCRIPTION:
Gynvael Coldwind has reported a vulnerability in Unreal Commander,
which can be exploited by malicious people to compromise a user's
system.
The vulnerability is caused due to an input validation error when
handling the filename of downloaded files through FTP. This can be
exploited to e.g. create files in arbitrary locations via directory
traversal attacks.
Successful exploitation requires that the user is e.g. tricked into
downloading a file with a specially-crafted filename from a malicious
FTP server.
The vulnerability is reported in versions 0.92 build 573 and 0.92
build 565. Other versions may also be affected.
SOLUTION:
Do not connect to untrusted FTP servers.
