Vulnerability Note VU#829422
Ethereal fails to properly handle malformed iSNS packets
Ethereal contains a vulnerability in the way it processes Internet Storage Name Service (iSNS) packets.
The Internet Storage Name Service (iSNS) protocol is used to automate the discovery, management, and configuration of iSCSI and Fibre Channel devices in an IP network. Ethereal includes the ability to decode packets containing iSNS data. There is a vulnerability in the way the iSNS dissector decodes malformed iSNS packets. By sending a malformed iSNS packet or convincing a victim to read a malformed packet trace file, a remote, unauthenticated attacker could cause Ethereal to crash or potentially execute code of the attacker's choice.
A remote, unauthenticated attacker could cause Ethereal to crash or potentially execute code of the attacker's choice.
Upgrade to version 0.10.5 or later.
1) Select Analyze->Enabled Protocols
2) Disable the iSNS protocol dissector from the list by unchecking its "Status" checkbox
However, it is strongly encouraged to upgrade to version 0.10.5 or later.
