accepted. In some cases, a system reboot may be necessary to recover normal system operation. To 
exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with 
a vulnerable system. 

In addition to these vulnerabilities, Cisco Nexus 5000 devices contain a TCP DoS vulnerability that 
may result in a system crash. This additional vulnerability was found as a result of testing the TCP 
state manipulation vulnerabilities. 

Cisco has released free software updates for download from the Cisco website that address these 
vulnerabilities. Workarounds that mitigate these vulnerabilities are available.
