Certain scripts in OpenServer before 5.0.6 allow local users to overwrite files and conduct other unauthorized activities via a symlink attack on temporary files.

Unknown vulnerability in SCO OpenServer 5.0.6 and earlier allows local users to modify critical information such as certain CPU registers and segment descriptors.

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.

snmpd in SCO OpenServer has an SNMP community string that is writable by default, which allows local attackers to modify the host's configuration.
