Solution  265488: A Security Vulnerability in Sun Virtual Desktop 
Infrastructure (VDI) Software 3.0 may Lead to Inadvertent use of an 
Insecure LDAP Connection

Bug ID: 6856923
Product: Sun Virtual Desktop Infrastructure
Date of Resolved Release: 14-Aug-2009

SA Document Body
A security vulnerability in Sun Virtual Desktop Infrastructure (VDI) 
Software 3.0 may lead to inadvertent use of an insecure LDAP connection:

1. Impact

A security vulnerability in Sun Virtual Desktop Infrastructure (VDI) 
Software 3.0 may allow a remote privileged user to be able to view 
client LDAP requests for VDI configuration data.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform
Sun VDI Software 3.0 (for Solaris 10) without patch 141481-02
x86 Platform
Sun VDI Software 3.0 (for Solaris 10) without patch 141482-02
Note 1: Sun VDI 2.0 does not provide integration with LDAP directories 
and therefore is not impacted by this issue.

To determine the version of Sun Virtual Desktop Infrastructure Software 
on a system, the following command can be run:
     $ /usr/bin/pkginfo -l SUNWvda-service  |  grep -i version
Note 2: Only systems which have been setup to use a secure LDAP 
connection are vulnerable to this issue. To determine if a system has 
been set up in this way, execute the following command:
     # /opt/SUNWvda/sbin/vda directory-show
     Authentication: secure
     ...
3. Symptoms

There are no predictable symptoms that would indicate the described 
issue has been exploited.

Unless the LDAP User Directory has an insecure configuration, the Sun 
VDI 3.0 service will not function.

4. Workaround

To work around this issue, anonymous binding should be disabled (using 
ACLs or other settings, depending on the type of LDAP directory used) on 
the LDAP directory to prevent the silent fallback to unencrypted connection.

5. Resolution

This issue is addressed in the following releases:

SPARC Platform
Sun VDI Software 3.0 (for Solaris 10) with patch 141481-02 or later
x86 Platform
Sun VDI Software 3.0 (for Solaris 10) with patch 141482-02 or later
