Sun Ray Server Software 4.0

Date of Resolved Release
15-Jul-2009

Two Security Vulnerabilities in Sun Ray Server Software 4.0 on Systems with Trusted Extensions Enabled May Allow either a Denial of Service (DoS) of the Audio Service or Unauthorized Access to Other Users' Sessions

1. Impact

A security vulnerability in the Sun Ray Server Software (SRSS) utaudiod daemon audio service may allow a local unprivileged user to cause a denial of audio service or possibly to execute arbitrary code with the privileges of the utaudiod service.  A second vulnerability, an information leak in the utaudiod daemon, may allow a local unprivileged user on a system with Trusted Extensions enabled to gain unauthorized access to the Sun Ray sessions of other users.

2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform:

• Sun Ray Server Software 4.0 (for Solaris 10) without patch 127553-06

x86 Platform:

• Sun Ray Server Software 4.0 (for Solaris 10) without patch 127554-06

Notes:

1. Sun Ray Server Software 2.0, 3.0, 3.1, 3.1.1 and 4.1 are not affected by these issues.

To determine the version of Sun Ray Server Software on a system, the following command can be run:

$/opt/SUNWut/lib/utprodinfo -p SUNWuto VERSION
4.0_48

2. These issues can only occur on systems with Trusted Extensions enabled.

To determine if a system is configured with Solaris Trusted Extensions, the following command can be run:

$ svcs /system/labeld
STATE          STIME    FMRI
online         7:08:09  svc:/system/labeld:default

If the system is configured with Solaris Trusted Extensions, the "labeld" service will have an instance in the online state.

3. Symptoms

There are no predictable symptoms that would indicate the described vulnerabilities have been exploited.

4. Workaround

There is no workaround for these issues. Please see the Resolution section below.

5. Resolution

These issues are addressed in the following releases:

SPARC Platform:

• Sun Ray Server Software 4.0 (for Solaris 10) with patch 127553-06 or later

x86 Platform:

• Sun Ray Server Software 4.0 (for Solaris 10) with patch 127554-06 or later
