   SA Document Body

   A Security Vulnerability in the Logical Domains (LDoms) Manager May Allow
   Unauthorized System Access and Escalation of Privileges

   1. Impact

   A security vulnerability in the Logical Domains (LDoms) Manager
   (ldm(1M)) may allow a local unprivileged user to circumvent SPARC
   Firmware password protection and thus gain unauthorized access to data
   or gain elevated privileges on the system.

   2. Contributing Factors

   SPARC Platform:

   * Logical Domain Manager 1.0 without patch 139395-02
   * Logical Domain Manager 1.0.1 without patch 139396-02
   * Logical Domain Manager 1.0.2 without patch 139397-02
   * Logical Domain Manager 1.0.3 without patch 139398-01

   Note: The x86 Platform is not affected by this issue, as Logical
   Domains (LDoms) software is supported only on the Sun SPARC Platform.
   To determine the version of the Logical Domains (LDoms) Manager
   installed on the system, the ldm(1M) command may be used:

   $ /opt/SUNWldm/bin/ldm -V
   Logical Domain Manager (v 1.0.3)
   Hypervisor control protocol v 1.1
   Using Hypervisor MD v 1.1
   System PROM:
   Hypervisor  v.1.6.1     @(#)Hypervisor 1.6.1 2008/02/11 12:15\015
   OpenBoot    v.4.28.1    @(#)OBP 4.28.1 2008/02/11 13:04

   3. Symptoms

   There are no predictable symptoms to indicate this issue has been
   exploited to gain unauthorized access to data or elevated privileges.
