CVE-2012-6057: Integer Overflow
First published: Wed Dec 05 2012(Updated: )
The dissect_eigrp_metric_comm function in epan/dissectors/packet-eigrp.c in the EIGRP dissector in Wireshark 1.8.x before 1.8.4 uses the wrong data type for a certain offset value, which allows remote attackers to cause a denial of service (integer overflow and infinite loop) via a malformed packet.
