Description

IRIX contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when a malicious user bypasses Network File System (NFS) access checks when the root,rw or access options in /etc/exports contain only wildcards (IP addresses or domain suffixes) and no explicit hostnames or netgroups. This flaw may lead to a loss of integrity.
