CVE-2015-0640
HighSummary
The high-speed logging (HSL) feature in Cisco IOS XE 2.x and 3.x before version 3.10.4S and other specified versions is vulnerable to remote attacks that can lead to denial of service by sending large IP packets requiring NAT and HSL processing after fragmentation.
Risk Assessment
Attackers can exploit this vulnerability to remotely reload the device, resulting in service availability interruptions.
Recommendation
It is recommended to update the software to the latest version to mitigate this vulnerability and to monitor network traffic for potential attacks.
