Synopsis :

The remote device is missing a vendor-supplied security patch.

Description :

Cisco IOS XE Software for 1000 Series Aggregation Services Routers
(ASR) contains the following denial of service (DoS) vulnerabilities :

- Cisco IOS XE Software TCP Segment Reassembly Denial of
Service Vulnerability (CVE-2013-5543)

- Cisco IOS XE Software Malformed EoGRE Packet Denial of
Service Vulnerability (CVE-2013-5545)

- Cisco IOS XE Software Malformed ICMP Packet Denial of
Service Vulnerability (CVE-2013-5546)

- Cisco IOS XE Software PPTP Traffic Denial of Service
Vulnerability (CVE-2013-5547)

These vulnerabilities are independent of each other. A release that is
affected by one of the vulnerabilities may not be affected by the
others.

Successful exploitation of any of these vulnerabilities allows an
unauthenticated, remote attacker to trigger a reload of the Embedded
Services Processors (ESP) card or the Route Processor (RP) card, which
causes an interruption of services.

Repeated exploitation can result in a sustained DoS condition.
