IRIX and ProPack contain a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when an error in arrayd occurs during the processing of authentication requests when configured to use NONE or SIMPLE authentication. Use of the classic exploit may grant a malicious user remote root and lead to a loss of integrity.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: switch to NOREMOTE authentication.
