CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
BulletProof FTP Client 2.x
http://secunia.com/advisories/product/12284/

DESCRIPTION:
His0k4 has discovered a vulnerability in BulletProof FTP Client,
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 server names. This can be exploited to cause a stack-based buffer
overflow by tricking a user into attempting to connect to a server
with an overly long name (e.g. by importing a malicious site list and
then connecting to a specified server).

The vulnerability is confirmed in version 2.63 Build 56. Other
versions may also be affected.

SOLUTION:
Do not import untrusted site lists nor attempt to connect to servers
with long names.
