SECUNIA ADVISORY ID:
SA16552

VERIFY ADVISORY:
http://secunia.com/advisories/16552/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
LeapFTP 2.x
http://secunia.com/product/1673/

DESCRIPTION:
Sowhat has reported a vulnerability in LeapFTP, which potentially can
be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error when handling a
site queue file (.lsq) containing an overly long host name. This can
be exploited to cause a buffer overflow and may allow execution of
arbitrary code.

Successful exploitation requires that the user is tricked into
opening a specially crafted ".lsq" file in LeapFTP or by
double-clicking on it in Explorer.

The vulnerability has been reported in versions 2.7.0 through 2.7.5.

SOLUTION:
Update to version 2.7.6.
