Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The dissect_ppi function in epan/dissectors/packet-ppi.c in the PPI dissector in Wireshark 2.0.x before 2.0.1 does not initialize a packet-header data structure, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

Install update from vendor's website.
