DESCRIPTION:
Luigi Auriemma has discovered a vulnerability in Samsung AllShare,
which can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to a NULL pointer dereference error
in the libpin3_dll.dll module when processing HTTP headers. This can
be exploited to cause the application to crash via a large value in
the "Content-Length" header sent to TCP port 9500.

The vulnerability is confirmed in version 2.1.0.12031_10. Other
versions may also be affected.

SOLUTION:
Restrict access to trusted hosts only.
