Description

The VeloCloud Edge and Gateway exhibit an out-of-bounds write vulnerability when processing tunneled IP fragments between authenticated overlay neighbors. This vulnerability impacts the VeloCloud VCMP tunnel protocol only. A successful exploit can cause the affected process to terminate and restart, leading to a temporary disruption of traffic. Hosts on the internet that are unauthenticated and unable to form an overlay peer relationship can not trigger the vulnerable logic.
