IBM AIX contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered by an insecure default configuration of UUCP where users can aquire root privileges. This flaw may lead to a loss of confidentiality and/or integrity.
Upgrade AIX with the fix ix18516 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround(s): disable uucp using the command "chmod 0100 /usr/bin/uucp"
AIX version 3 is not recommended by IBM for production systems
