DESCRIPTION:
A vulnerability has been discovered in Wireshark, which can be
exploited by malicious people to cause a DoS (Denial of Service) or
potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the
"dissect_enttec_dmx_data()" function
(epan/dissectors/packet-enttec.c) when processing RLE Compressed DMX
data of the ENTTEC protocol. This can be exploited to cause a buffer
overflow via a specially crafted packet sent to UDP port 3333.

Successful exploitation may allow execution of arbitrary code. 

The vulnerability is confirmed in version 1.4.2. Other versions may
also be affected.

SOLUTION:
Fixed in the SVN repository.

PROVIDED AND/OR DISCOVERED BY:
Reported by non-customers in a Wireshark bug report.
