Description

IRIX contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when the netprint program calls the disable command via a system() call without supplying an absolute path. The PATH environment variable for finding and executing the disable program can be trivially modified by a malicious user. This flaw may lead to a loss of integrity.

Take note that the 2022 patch for version 6.2 will patch all vulnerable versions and is the only patch available for other versions. For example, in the patch directory for 6.1 or 6.3, there is no patch for this vulnerability. As a result, the 2022 for 6.2 must be used.
