The SNMP module in Cisco NX-OS 7.0(3)N1(1) and earlier on Nexus 5000 and 6000 devices provides different error messages for invalid requests depending on whether the VLAN ID exists, which allows remote attackers to enumerate VLANs via a series of requests, aka Bug ID CSCup85616.

Buffer overflow in the Smart Call Home implementation in Cisco NX-OS on Fabric Interconnects in Cisco Unified Computing System 1.4 before 1.4(1i), NX-OS 5.0 before 5.0(3)U2(2) on Nexus 3000 devices, NX-OS 4.1 before 4.1(2)E1(1l) on Nexus 4000 devices, NX-OS 5.x before 5.1(3)N1(1) on Nexus 5000 devices, NX-OS 5.2 before 5.2(3a) on Nexus 7000 devices, and CG-OS CG4 before CG4(2) on Connected 1000 Connected Grid Routers allows remote SMTP servers to execute arbitrary code via a crafted reply, aka Bug IDs CSCtk00695, CSCts56633, CSCts56632, CSCts56628, CSCug14405, and CSCuf61322.

The JAR files on Cisco Device Manager for Cisco MDS 9000 devices before 5.2.8, and Cisco Device Manager for Cisco Nexus 5000 devices, allow remote attackers to execute arbitrary commands on Windows client machines via a crafted element-manager.jnlp file, aka Bug IDs CSCty17417 and CSCty10802.

Memory leak in libcmd in Cisco NX-OS 5.0 on Nexus switches allows remote authenticated users to cause a denial of service (memory consumption) via SNMP requests, aka Bug ID CSCtr65682.
