CVE-2016-1467

CWE-399

Summary

A vulnerability in system resource management in the Cisco Videoscape Session
Resource Manager (VSRM) could allow an unauthenticated, adjacent attacker to 
cause a denial of service (DoS) condition because the device unexpectedly 
restarts.

The vulnerability occurs because the VSRM is not installed using best 
practices and in a secure environment where DoS attacks are prevented before 
reaching the adjacent network. An attacker could exploit this vulnerability 
only by being on the adjacent network and directing a flood of traffic at the
devices upstream to the VSRM. An exploit could allow the attacker to cause a 
DoS condition. The VSRM resumes normal operation when the attack ceases on the
upstream devices.

Cisco has not released software updates that address this vulnerability. 
Workarounds that address this vulnerability are not available.
