5.0
2016-05-25 CVE-2016-1407 Improper Input Validation vulnerability in Cisco IOS XR
Cisco IOS XR through 5.3.2 mishandles Local Packet Transport Services (LPTS) flow-base entries, which allows remote attackers to cause a denial of service (session drop) by making many connection attempts to open TCP ports, aka Bug ID CSCux95576.

5.0
2016-03-24 CVE-2016-1366 Permissions, Privileges, and Access Controls vulnerability in Cisco IOS XR
The SCP and SFTP modules in Cisco IOS XR 5.0.0 through 5.2.5 on Network Convergence System 6000 devices use weak permissions for system files, which allows remote authenticated users to cause a denial of service (overwrite) via unspecified vectors, aka Bug ID CSCuw75848.

cisco CWE-264
6.8
2015-07-23 CVE-2015-4285 Resource Management Errors vulnerability in Cisco IOS XR
The Local Packet Transport Services (LPTS) implementation in Cisco IOS XR 5.1.2, 5.1.3, 5.2.1, and 5.2.2 on ASR9k devices makes incorrect decisions about the opening of TCP and UDP ports during the processing of flow base entries, which allows remote attackers to cause a denial of service (resource consumption) by sending traffic to these ports continuously, aka Bug ID CSCur88273.

cisco CWE-399
5.0
2015-06-19 CVE-2015-4191 Resource Management Errors vulnerability in Cisco IOS XR 5.2.1
Cisco IOS XR 5.2.1 allows remote attackers to cause a denial of service (ipv6_io service reload) via a malformed IPv6 packet, aka Bug ID CSCuq95565.
network
low complexity
cisco CWE-399
5.0
2015-04-17 CVE-2015-0695 Resource Management Errors vulnerability in Cisco IOS XR
Cisco IOS XR 4.3.4 through 5.3.0 on ASR 9000 devices, when uRPF, PBR, QoS, or an ACL is configured, does not properly handle bridge-group virtual interface (BVI) traffic, which allows remote attackers to cause a denial of service (chip and card hangs and reloads) by triggering use of a BVI interface for IPv4 packets, aka Bug ID CSCur62957.
network
low complexity
cisco CWE-399
7.8
2015-02-21 CVE-2015-0618 Data Processing Errors vulnerability in Cisco Carrier Routing System and IOS XR
Cisco IOS XR 5.0.1 and 5.2.1 on Network Convergence System (NCS) 6000 devices and 5.1.3 and 5.1.4 on Carrier Routing System X (CRS-X) devices allows remote attackers to cause a denial of service (line-card reload) via malformed IPv6 packets with extension headers, aka Bug ID CSCuq95241.
