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.

Buffer overflow in cron in Caldera UnixWare 7 allows local users to execute arbitrary code via a command line argument.

The timed program (in.timed) in UnixWare 7 and OpenUnix 8.0.0 does not properly terminate certain strings with a null, which allows remote attackers to cause a denial of service.

Directory traversal vulnerability in (1) pkgadd and (2) pkgrm in SCO UnixWare 7.1.4 allows local users to gain privileges via unknown vectors.

Directory traversal vulnerability in pkgadd in SCO UnixWare 7.1.4 before p534589 allows local users to create or append to arbitrary files via ".." sequences in an unspecified environment variable, probably PKGINST.

The installation process in IBM InfoSphere Information Server 8.1, 8.5, 8.7, and 9.1 on UNIX and Linux sets incorrect permissions and ownerships for unspecified files, which allows local users to bypass intended access restrictions via standard filesystem operations.
