http://secunia.com/advisories/25248/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
TinyIdentD 2.x

DESCRIPTION:
Maarten Boone has discovered a vulnerability in TinyIdentD, which can
be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error when processing
query requests. This can be exploited to cause a stack-based buffer
overflow via an overly long (greater than 512 bytes) query request
sent to default port 113/TCP (Identification Protocol).

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 2.2. Other versions may
also be affected.

SOLUTION:
Restrict access to port 113.
