DESCRIPTION:
Multiple vulnerabilities have been reported in Wireshark, which can
be exploited by malicious people to cause a DoS (Denial of Service).

1) A NULL pointer dereference error in the ANSI A dissector can be
exploited to cause a crash via a specially crafted packet.

2) An error in the IEEE 802.11 dissector can be exploited to cause an
infinite loop via a specially crafted packet.

This vulnerability is reported in versions 1.6.0 through 1.6.5 only.

3) An error in the MP2T dissector when allocating memory can be
exploited to cause a crash via a specially crafted packet.

NOTE: A weakness exists in the pcap and pcap-ng file parsers when
reading ERF data and can cause a crash via a specially crafted trace
file.

The vulnerabilities are reported in versions 1.4.0 through 1.4.11 and
1.6.0 through 1.6.5.

SOLUTION:
Update to version 1.4.12 or 1.6.6.

PROVIDED AND/OR DISCOVERED BY:
