Cisco IOS XE Software IP Fragment Reassembly Denial of Service Vulnerability
vendor_cisco·2016-09-28·CVSS 7.8
CVE-2016-6386 [HIGH] CWE-399 Cisco IOS XE Software IP Fragment Reassembly Denial of Service Vulnerability
Cisco IOS XE Software IP Fragment Reassembly Denial of Service Vulnerability
A vulnerability in the IPv4 fragment reassembly function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload.
The vulnerability is due to the corruption of an internal data structure that occurs when the affected software reassembles an IPv4 packet. An attacker could exploit this vulnerability by sending crafted IPv4 fragments to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
