Solution Type Sun Alert
Solution 253889 : 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
Bug ID : 6672502
Product : Sun Ray Server Software 4.0
Date of Resolved Release : 15-Jul-2009
SA Document Body
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
