Buffer overflow in the Strcmp function in the XKEYBOARD extension in X Window System X11R6.4 and earlier, as used in SCO UnixWare 7.1.3 and Sun Solaris 8 through 10, allows local users to gain privileges via a long _XKB_CHARSET environment variable value.

Unspecified vulnerability in ptrace in SCO UnixWare 7.1.3 and 7.1.4 allows local users to gain privileges via unspecified vectors.

Buffer overflow in uidadmin in SCO Unixware 7.1.3 and 7.1.4 allows local users to execute arbitrary code via a -S (scheme) argument that specifies a large file, a different vulnerability than CVE-2001-1063.

Stack-based buffer overflow in ppp in SCO Unixware 7.1.3 and 7.1.4, and possibly earlier versions, allows local users to execute arbitrary code via a long argument to the (1) prompt or (2) defprompt command.

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.

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.

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.
