Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

epan/dissectors/packet-diameter.c in the DIAMETER dissector in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 does not properly construct certain array data structures, which allows remote attackers to cause a denial of service (application crash) via a crafted packet that triggers incorrect memory allocation.
