TITLE:
Trellian FTP PASV Response Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA39370

VERIFY ADVISORY:
http://secunia.com/advisories/39370/

DESCRIPTION:
A vulnerability has been discovered in Trellian FTP, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing
FTP responses. This can be exploited to cause a stack-based buffer
overflow via an overly long PASV response.

Successful exploitation allows execution of arbitrary code, but
requires that the user is tricked into connecting to a malicious FTP
server.

The vulnerability is confirmed in version 3.1.3.1789. Other versions
may also be affected.

SOLUTION:
Do not connect to untrusted FTP servers.

PROVIDED AND/OR DISCOVERED BY:
