-----BEGIN PGP SIGNED MESSAGE----- =============================================================================== Security Advisory CERT-NL =============================================================================== Author/Source : Egon Verharen Index : S-99-20 Distribution : World Page : 1 Classification: External Version: 1 Subject : Array Services default configuration Date : 19-Jul-99 =============================================================================== By courtesy of CERT Coordination Center we received the following information. CERT Coordination Center advisory CA-99-09 Array Services default configuration on IRIX and UNICOS systems running the Array Services daemon. A vulnerability has been discovered in the default configuration of the Array Services daemon, arrayd. Array Services are used to manage a cluster of systems. The default configuration file, arrayd.auth, disables authentication and does not provide adequate protection for systems connected to an untrusted network, allowing remote and local users to execute arbitrary commands as root. This advisory provides a solution for the affected systems. CERT-NL recommends installing the named patches for your systems immediately, or contact your vendor. Additional information with regards to this vulnerability is placed in the advisory.
