Cisco Nx-os any version

The BGP implementation in Cisco NX-OS does not properly filter AS paths, which allows remote attackers to cause a denial of service (BGP service reset and resync) via a malformed UPDATE message, aka Bug ID CSCtn13055.

Cisco NX-OS on the Nexus 7000, when a certain Overlay Transport Virtualization (OTV) configuration is used, allows remote attackers to cause a denial of service (M1-Series module reload) via crafted packets, aka Bug ID CSCud15673.

The Label Distribution Protocol (LDP) functionality in Cisco NX-OS allows remote attackers to cause a denial of service (temporary LDP session outage) via LDP discovery traffic containing malformed Hello messages, aka Bug ID CSCul88851.

The ACL implementation in Cisco NX-OS 5.0(2) and 5.0(3) before 5.0(3)N2(1) on Nexus 5000 series switches, and NX-OS before 5.0(3)U1(2a) on Nexus 3000 series switches, does not properly handle comments in conjunction with deny statements, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by sending packets, aka Bug IDs CSCto09813 and CSCtr61490.

Cisco NX-OS 5.0 and earlier on MDS 9000 devices allows remote attackers to cause a denial of service (supervisor CPU consumption) via Authentication Header (AH) authentication in a Virtual Router Redundancy Protocol (VRRP) frame, aka Bug ID CSCte27874.

Cisco NX-OS on the Nexus 1000V does not assign the proper priority to heartbeat messages from a Virtual Ethernet Module (VEM) to a Virtual Supervisor Module (VSM), which allows remote attackers to cause a denial of service (false VEM unavailability report) via a flood of UDP packets, aka Bug ID CSCud14840.

Cisco NX-OS on the Nexus 1000V does not properly handle authentication for Virtual Ethernet Module (VEM) to Virtual Supervisor Module (VSM) communication, which allows remote attackers to obtain VEM access via (1) spoofed STUN packets or (2) a crafted VMware ESXi instance, aka Bug ID CSCud14832.

The encryption functionality in the Virtual Supervisor Module (VSM) to Virtual Ethernet Module (VEM) communication component in Cisco NX-OS on the Nexus 1000V does not properly authenticate VSM/VEM packets, which allows remote attackers to disable packet-level encryption and integrity protection via crafted packets, aka Bug ID CSCud14710.

Cisco NX-OS on Nexus 7000 series switches does not properly handle certain line-card replacements, which might allow remote authenticated users to cause a denial of service (memory consumption) via a crafted configuration that references interfaces that do not exist on the new card, aka Bug ID CSCud44300.

The TACACS+ command-authorization implementation in Cisco NX-OS allows local users to cause a denial of service (device reload) via a long CLI command, aka Bug ID CSCur54182.

The HSRP implementation in Cisco NX-OS 6.2(2a) and earlier allows remote attackers to bypass authentication and cause a denial of service (group-member state modification and traffic blackholing) via malformed HSRP packets, aka Bug ID CSCup11309.

Directory traversal vulnerability in tar in Cisco NX-OS allows local users to access arbitrary files via crafted command-line arguments, aka Bug IDs CSCty07157, CSCty07159, CSCty07162, and CSCty07164.

Directory traversal vulnerability in the command-line interface in Cisco NX-OS 6.2(2a) and earlier allows local users to read arbitrary files via unspecified input, aka Bug ID CSCul05217.

Directory traversal vulnerability in filesys in Cisco NX-OS 6.1(2) and earlier allows local users to access arbitrary files via crafted command-line arguments during a delete action, aka Bug IDs CSCty07270, CSCty07271, CSCty07273, and CSCty07275.

The BGP implementation in Cisco NX-OS 6.2(2a) and earlier does not properly handle the interaction of UPDATE messages with IPv6, VPNv4, and VPNv6 labeled unicast-address families, which allows remote attackers to cause a denial of service (peer reset) via a crafted message, aka Bug ID CSCuj03174.

The BGP implementation in Cisco NX-OS does not properly filter AS paths, which allows remote attackers to cause a denial of service (BGP service reset and resync) via a malformed UPDATE message, aka Bug ID CSCtn13065.

The BGP implementation in Cisco NX-OS does not properly filter segment types in AS paths, which allows remote attackers to cause a denial of service (BGP service reset) via a malformed UPDATE message, aka Bug ID CSCtn13043.

The management interface in Cisco NX-OS on Nexus 7000 devices allows remote authenticated users to obtain sensitive configuration-file information by leveraging the network-operator role, aka Bug ID CSCti09089.
