Some vulnerabilities have been reported in OpenVMS, which can be exploited by malicious, local users and by malicious people to cause a DoS (Denial of Service).
1) A boundary error exists within the NET$CSMACD.EXE image. This can be exploited to cause a buffer overflow by issuing the "MCR MCL SHOW CSMA-CD Port * All" command.
2) An error exists within the SYS$EI1000.EXE and SYS$EI1000_MON.EXE images when handling network packets. This can be exploited to crash an affected system by sending specially crafted, overly long network packets.
