corosync: Corosync: Denial of Service via integer overflow in join message validation
A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol UDP packets. This can cause the service to crash, leading to a denial of service. This vulnerability...
corosync: Corosync: Denial of Service and information disclosure via crafted UDP packet
A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol UDP packet. This can lead to an out-of-bounds read, causing a denial of service...
