Vulnerability Note VU#119876Ethereal contains multiple vulnerabilities in the EIGRP protocol dissectorOverviewEthereal contains multiple vulnerabilities in the Enhanced Interior Gateway Routing Protocol (EIGRP) protocol dissector. These vulnerabilities could allow a remote, unauthenticated attacker to execute arbitrary code.I. DescriptionEthereal is a network traffic analysis package. It includes the ability to decode packets containing EIGRP data. There are two buffer overflow vulnerabilities in the way the EIGRP protocol dissector decodes packets containing EIGRP data. These vulnerabilities could be exploited by a remote, unauthenticated attacker by sending a specially crafted EIGRP packet containing overly long IP address values. Exploitation of these vulnerabilities could result in arbitrary code execution.II. ImpactA remote, unauthenticated attacker could execute arbitrary code on the vulnerable system.III. SolutionUpgradeUpgrade to version 0.10.3 or later.
2) Deselect the EIGRP protocol dissector from the list (for Ethereal versions 0.10.x)
2) Disable the EIGRP protocol dissector from the list by unchecking its "Status" checkbox Systems Affected
