CVE-2014-3293

Cisco IOS 15.4(3)S0b on ASR901 devices makes incorrect decisions to use the CPU for IPv4 packet processing, which allows remote attackers to cause a denial of service (BGP neighbor flapping) by sending many crafted IPv4 packets, aka Bug ID CSCuo29736.

Lower severity and a low EPSS score (1.74%). Track it; it rarely justifies an emergency change on its own.
