Sco Open Unix 8.0

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.

Safe.pm 2.0.7 and earlier, when used in Perl 5.8.0 and earlier, may allow attackers to break out of safe compartments in (1) Safe::reval or (2) Safe::rdo using a redefined @_ variable, which is not reset between successive calls.

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.
