AusCERT recommends administrators consider risk reduction strategies such as reviewing user access to local network devices and introducing internal DoS mitigation techniques. - --------------------------BEGIN INCLUDED TEXT-------------------- Cisco Security Advisory Cisco Videoscape Session Resource Manager Denial of Service Vulnerability Medium Advisory ID: cisco-sa-20160727-vsrm Published: 2016 July 27 16:00 GMT Version 1.0: Final CVSS Score: Base - 4.6 Workarounds: No workarounds available Cisco Bug IDs: CSCva01813 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. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160727-vsrm Affected Products Vulnerable Products All versions of Cisco VSRM are vulnerable. Products Confirmed Not Vulnerable No other Cisco products are currently known to be affected by this vulnerability. Workarounds Workarounds that address this vulnerability are not available. Fixed Software Cisco provides information about fixed software in Cisco bugs, which are accessible through the Cisco Bug Search Tool. When considering software upgrades, customers are advised to consult the Cisco Security Advisories and Responses archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release.
