XHA (Linux-HA) on the BlueCat Networks Adonis DNS/DHCP Appliance 5.0.2.8 allows remote attackers to cause a denial of service (heartbeat control process crash) via a UDP packet to port 694. NOTE: this may be the same as CVE-2006-3121.
heartbeat.c in heartbeat before 2.0.6 sets insecure permissions in a shmget call for shared memory, which allows local users to cause an unspecified denial of service via unknown vectors, possibly during a short time window on startup.
