The problem is Bug ID CSCti23447 , CSCti49507 ,and CSCtj01991 It is a problem.Malformed by a third party IP Service disruption via packets (NetStack Process crash and device reload ) There is a possibility of being put into a state. Adopt the Cisco Nexus OS operating system. Cisco NX-OS software is affected by this vulnerability when the operating system IP stack processes malformed IP packets and obtains Layer 4 (UDP or TCP) information from the packets, which can cause the Cisco Nexus 1000v, 5000 to run software affected by this vulnerability. And 7000 series switches are overloaded. An attacker can exploit this issue to cause the device to crash, denying service to legitimate users. The Cisco Nexus family consists of a comprehensive switch offering that enables customers to gradually and cost-effectively migrate to 10 Gigabit Ethernet and unified data center fabrics. ----------------------------------------------------------------------

Cisco has released free software updates that address this vulnerability.
Cisco NX-OS Software versions prior to the First Fixed Release version are affected. Refer to the Software Versions and Fixes section for details regarding fixed versions.
To determine the version of Cisco NX-OS Software that is running on a Cisco Nexus switch, administrators can log in to the device and issue the "show version" command to display the system banner. The following example shows how to display the version information for the kickstart and system image that is running on a device that runs Cisco NX-OS Release 5.1(3):

Products Confirmed Not Vulnerable +--------------------------------
Cisco NX-OS Software for products other than the Cisco Nexus 1000v, 5000, and 7000 Series Switches is not affected by this vulnerability. In this case, an ICMP error message (time exceeded) needs to be generated. During generation of this ICMP message, the bug could be triggered.
-
Policy-based routing is in use, and to make a routing decision, an incoming packet needs to be parsed. If the packet is a malformed TCP segment and the routing policy uses TCP information for routing decisions, then this bug could be triggered.
-
An egress Access Control List (ACL) is applied to an interface and a malformed IP packet that needs to be forwarded through that interface is received.
Note: This list is not exhaustive. It contains some of the scenarios that have been confirmed to trigger the vulnerability described in this document.
Both through-the-device (transit) traffic and to-the-device traffic may trigger this vulnerability.
When a system reloads because of this vulnerability, a process called "netstack" will terminate unexpectedly, and the following message will be recorded to the system log:
2012 Feb 02 20:32:15 NX-7010 %SYSMGR-2-SERVICE_CRASHED: Service "netstack" (PID 4335) hasn't caught signal 11 (core will be saved). The fix was completed with
CSCti49507. The CVSS scoring in this security advisory is in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response.
Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks.
Cisco has provided additional information regarding CVSS at the following link:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link:
http://intellishield.cisco.com/security/alertmanager/cvss
- CSCti23447, CSCti49507, and CSCtj01991 ("Malformed IP packet causes Netstack crash")
CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete
CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed
Impact
Successful exploitation of the vulnerability that is described in this advisory may result in a reload of an affected device. Repeated exploitation could result in a sustained DoS condition.
Software Versions and Fixes
When considering software upgrades, customers are advised to consult the Cisco Security Advisories and Responses archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
Each row of the Cisco NX-OS Software table (below) names a Cisco NX-OS Software release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the First Fixed Release column of the table. A device that is running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable.
Obtaining Fixed Software
Cisco has released free software updates that address the vulnerability|vulnerabilities described in this advisory. Prior to deploying software, customers are advised to consult their maintenance providers or check the software for feature set compatibility and known issues that are specific to their environments.
Customers may only install and expect support for feature sets they have purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html, or as set forth at http://www.cisco.com/public/sw-center/sw-usingswc.shtml.

"data": "Cisco NX-OS 4.2.x before 4.2(1)SV1(5.1) on Nexus 1000v series switches; 4.x and 5.0.x before 5.0(2)N1(1) on Nexus 5000 series switches; and 4.2.x before 4.2.8, 5.0.x before 5.0.5, and 5.1.x before 5.1.1 on Nexus 7000 series switches allows remote attackers to cause a denial of service (netstack process crash and device reload) via a malformed IP packet, aka Bug IDs CSCti23447, CSCti49507, and CSCtj01991. The problem is Bug ID CSCti23447 , CSCti49507 ,and CSCtj01991 It is a problem.Malformed by a third party IP Service disruption via packets (NetStack Process crash and device reload ) There is a possibility of being put into a state. Adopt the Cisco Nexus OS operating system. Cisco NX-OS software is affected by this vulnerability when the operating system IP stack processes malformed IP packets and obtains Layer 4 (UDP or TCP) information from the packets, which can cause the Cisco Nexus 1000v, 5000 to run software affected by this vulnerability. And 7000 series switches are overloaded. \nAn attacker can exploit this issue to cause the device to crash, denying service to legitimate users. The Cisco Nexus family consists of a comprehensive switch offering that enables customers to gradually and cost-effectively migrate to 10 Gigabit Ethernet and unified data center fabrics. ----------------------------------------------------------------------\n\nSecunia presentations @ RSA Conference 2012, San Francisco, USA, 27 Feb-02 March\nListen to our Chief Security Specialist, Research Analyst Director, and Director Product Management \u0026 Quality Assurance discuss the industry\u0027s key topics.

In\n this case, an ICMP error message (time exceeded) needs to be\n generated. During generation of this ICMP message, the bug could\n be triggered. \n\n * Policy-based routing is in use, and to make a routing decision,\n an incoming packet needs to be parsed. If the packet is a\n malformed TCP segment and the routing policy uses TCP information\n for routing decisions, then this bug could be triggered. \n\n * An egress Access Control List (ACL) is applied to an interface\n and a malformed IP packet that needs to be forwarded through that\n interface is received. \n\nNote: This list is not exhaustive. It contains some of the scenarios\nthat have been confirmed to trigger the vulnerability described in this\ndocument. \n\nBoth through-the-device (transit) traffic and to-the-device traffic may\ntrigger this vulnerability. \n\nWhen a system reloads because of this vulnerability, a process called\n\"netstack\" will terminate unexpectedly, and the following message will\nbe recorded to the system log:\n\n 2012 Feb 02 20:32:15 NX-7010 %SYSMGR-2-SERVICE_CRASHED: Service \"netstack\" (PID 4335) hasn\u0027t caught signal 11 (core will be saved). The fix was completed with\nCSCti49507. The CVSS scoring in this\nsecurity advisory is in accordance with CVSS version 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps organizations determine the urgency and priority\nof a response. \n\nCisco has provided a base and temporal score. Customers can also\ncompute environmental scores that help determine the impact of the\nvulnerability in their own networks. \n\nCisco has provided additional information regarding CVSS at the\nfollowing link:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to compute the\nenvironmental impact for individual networks at the following link:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n* CSCti23447, CSCti49507, and CSCtj01991 (\"Malformed IP packet causes\nNetstack crash\")\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of the vulnerability that is described in\nthis advisory may result in a reload of an affected device. Repeated\nexploitation could result in a sustained DoS condition. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, customers are advised to\nconsult the Cisco Security Advisories and Responses archive at\nhttp://www.cisco.com/go/psirt and review subsequent advisories to\ndetermine exposure and a complete upgrade solution. \n\nIn all cases, customers should ensure that the devices to be upgraded\ncontain sufficient memory and confirm that current hardware and\nsoftware configurations will continue to be supported properly by the\nnew release. If the information is not clear, customers are advised\nto contact the Cisco Technical Assistance Center (TAC) or their\ncontracted maintenance providers. \n\nEach row of the Cisco NX-OS Software table (below) names a Cisco\nNX-OS Software release train. If a given release train is vulnerable,\nthen the earliest possible releases that contain the fix (along with\nthe anticipated date of availability for each, if applicable) are\nlisted in the First Fixed Release column of the table. A device that\nis running a release in the given train that is earlier than the\nrelease in a specific column (less than the First Fixed Release) is\nknown to be vulnerable. \n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address the\nvulnerability|vulnerabilities described in this advisory. Prior to\ndeploying software, customers are advised to consult their\nmaintenance providers or check the software for feature set\ncompatibility and known issues that are specific to their\nenvironments. \n\nCustomers may only install and expect support for feature\nsets they have purchased. By installing, downloading,\naccessing, or otherwise using such software upgrades, customers\nagree to follow the terms of the Cisco software license at\nhttp://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html,\nor as set forth at\nhttp://www.cisco.com/public/sw-center/sw-usingswc.shtml. \n\nDo not contact psirt@cisco.com or security-alert@cisco.com for\nsoftware upgrades. \n\nCustomers with Service Contracts\n+-------------------------------\n\nCustomers with contracts should obtain upgraded software through their\nregular update channels.
