{"vuid":"VU#119876","idnumber":"119876","name":"Ethereal contains multiple vulnerabilities in the EIGRP protocol dissector","keywords":["Ethereal","Enhanced Interior Gateway Routing Protocol","EIGRP protocol dissector","TLV_IP_INT","TLV_IP_EXT","IP address"],"overview":"Ethereal 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.","clean_desc":"Ethereal 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.","impact":"A remote, unauthenticated attacker could execute arbitrary code on the vulnerable system.","resolution":"Upgrade\nUpgrade to version 0.10.3 or later. Note: Ethereal is considered BETA software at this time.","workarounds":"Disable Dissector If you are unable to upgrade to version 0.10.3 or later, you can disable the EIGRP protocol dissector by performing the following actions in Ethereal: (for Ethereal versions 0.8.x and 0.9.x) 1) Select Edit->Protocols\n2) Deselect the EIGRP protocol dissector from the list (for Ethereal versions 0.10.x) 1) Select Analyze->Enabled Protocols\n2) Disable the EIGRP protocol dissector from the list by unchecking its \"Status\" checkbox","sysaffected":"","thanks":"Ethereal credits Stefan Esser for reporting these vulnerabilities.","author":"This document was written by Damon Morda.","public":["http://security.e-matters.de/advisories/032004.html","http://www.ethereal.com/appnotes/enpa-sa-00013.html","http://secunia.com/advisories/11185/"],"cveids":["CVE-2004-0176"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2004-03-24T14:16:10Z","publicdate":"2004-03-22T00:00:00Z","datefirstpublished":"2004-03-24T17:31:50Z","dateupdated":"2004-03-25T15:13:25Z","revision":18,"vrda_d1_directreport":"","vrda_d1_population":"","vrda_d1_impact":"","cam_widelyknown":"15","cam_exploitation":"0","cam_internetinfrastructure":"7","cam_population":"7","cam_impact":"17","cam_easeofexploitation":"10","cam_attackeraccessrequired":"20","cam_scorecurrent":"9.8175","cam_scorecurrentwidelyknown":"12.04875","cam_scorecurrentwidelyknownexploited":"20.97375","ipprotocol":"","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":9.8175,"vulnote":null}
