Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Linux kernel networking module for the Transparent Inter-Process Communication (TIPC) protocol. A remote unauthenticated attacker can send specially crafted traffic to the system, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the TIPC bearer is set up.
