The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.
Compaq Tru64 4.0 d allows remote attackers to cause a denial of service in (1) telnet, (2) FTP, (3) ypbind, (4) rpc.lockd, (5) snmp, (6) ttdbserverd, and possibly other services via a TCP SYN scan, as demonstrated using nmap.
The Software Development Kit (SDK) and Run Time Environment (RTE) 1.4.1 and 1.4.2 for Tru64 UNIX allows remote attackers to cause a denial of service (Java Virtual Machine hang) via object deserialization.
portmapper in Compaq Tru64 4.0G and 5.0A allows remote attackers to cause a denial of service via a flood of packets.
Compaq TruCluster 1.5 allows remote attackers to cause a denial of service via a port scan from a system that does not have a DNS PTR record, which causes the cluster to enter a "split-brain" state.
