RPC portmapper (rpcbind) in SCO UnixWare 7.1.1 m5, 7.1.3 mp5, and 7.1.4 mp2 allows remote attackers or local users to cause a denial of service (lack of response) via multiple invalid portmap requests.

The X server in SCO UnixWare 7.1.1, 7.1.3, and 7.1.4 does not properly create socket directories in /tmp, which could allow attackers to hijack local sockets.

The NFS mountd service on SCO UnixWare 7.1.1, 7.1.3, 7.1.4, and 7.0.1, and possibly other versions, when run from inetd, allows remote attackers to cause a denial of service (memory exhaustion) via a series of requests, which causes inetd to launch a separate process for each request.

main.c in cscope 15-4 and 15-5 creates temporary files with predictable filenames, which allows local users to overwrite arbitrary files via a symlink attack.

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

Unknown vulnerability in chroot on SCO UnixWare 7.1.1 through 7.1.4 allows local users to escape the chroot jail and conduct unauthorized activities.

ISC BIND 8.3.x before 8.3.7, and 8.4.x before 8.4.3, allows remote attackers to poison the cache via a malicious name server that returns negative responses with a large TTL (time-to-live) value.

SCO UnixWare 7.1.1, 7.1.3, and Open UNIX 8.0.0 allows local users to bypass protections for the "as" address space file for a process ID (PID) by obtaining a procfs file descriptor for the file and calling execve() on a setuid or setgid program, which leaves the descriptor open to the user.

Buffer overflow in CDE libDtHelp library allows local users to execute arbitrary code via (1) a modified DTHELPUSERSEARCHPATH environment variable and the Help feature, (2) DTSEARCHPATH, or (3) LOGNAME.

Buffer overflow in rpc.cmsd in SCO UnixWare 7.1.1 and Open UNIX 8.0.0 allows remote attackers to execute arbitrary commands via a long parameter to rtable_create (procedure 21).
