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.

Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.

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.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

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.
