CVE-2013-6982 is a vulnerability of currently unknown severity. The BGP implementation in Cisco NX-OS 6.2(2a) and earlier does not properly handle the interaction of UPDATE messages with IPv6, VPNv4, and VPNv6 labeled unicast-address families, which allows remote attackers to cause a denial of service (peer reset) via a crafted message, aka Bug ID CSCuj03174.. EPSS estimates a 2.83% chance of exploitation in the next 30 days.
