Two separate studies of mobile devices have found serious privacy and security issues. One of the studies found that smartphones and tablet PCs can be eavesdropped on when they are being used to make purchases, conduct online banking transactions, or access VPNs (virtual private networks). Another study uncovered a number of ways to break into Apple’s iOS, its operating system for mobile devices.

Cisco Security Advisory: Cisco IOS Software RSVP Denial of Service Vulnerability

Cisco IOS Software and Cisco IOS XE Software contain a vulnerability in the RSVP feature when used on a device configured with VPN routing and forwarding (VRF) instances. This vulnerability could allow an
unauthenticated, remote attacker to cause an interface wedge, which can lead to loss of connectivity, loss of routing protocol adjacency, and other denial of service (DoS) conditions. This vulnerability could be exploited repeatedly to cause an extended DoS condition.

A workaround is available to mitigate this vulnerability.

Cisco has released free software updates that address this
vulnerability. This advisory is available at the following link:
