Cisco IOS and IOS XE Software are prone to multiple remote denial-of-service vulnerabilities.
An attacker can exploit these issues to cause an affected device to reload, denying service to legitimate users.
These issues are being tracked by Cisco Bug IDs CSCur29331, CSCut47751, CSCut50727 and CSCuu76493.
