According to “techworld”, VMware and Cisco Systems released security fixes this week for serious vulnerabilities in networking virtualization and server software typically used in data centers.

Cisco patched a persistent denial-of-service vulnerability that could prevent the out-of-band management of Cisco Unified Computing System (UCS) E-Series Blade servers that are deployed in Cisco Integrated Services Routers Generation 2 (ISR G2).

The vulnerability is located in the SSH (Secure Shell) service of the Cisco Integrated Management Controller (Cisco IMC), a specialized micro-controller embedded in server motherboards that allows systems administrators to monitor and manage servers from outside their OS.

Cisco released version 2.3.1 of the Cisco IMC firmware for UCS E-Series servers on Monday. Customers need to use the Host Upgrade Utility in order to deploy the new firmware.

If left unpatched, an attacker could exploit the vulnerability by sending a specially crafted packet to the vulnerable SSH server, forcing the IMC to become unresponsive. This could impact the availability of the entire server.

VMware released security updates Thursday for its NSX and vCloud Networking and Security (vCNS) products in order to patch what the company called "a critical information disclosure" vulnerability. The company's advisory does not clarify what kind of information can be disclosed by exploiting the issue, but both the NSX and vCNS products are used for virtualizing network services.
