A security weakness in Solaris Trusted Extensions Policy configuration ...
1. Impact
A security weakness in Solaris Trusted Extensions Policy
configuration
may allow a remote unprivileged user who has authorized or unauthorized
access to the X server, to leverage an additional vulnerability which
could
lead to arbitrary code execution as a local privileged or unprivileged
user.
2. Contributing Factors
This issue is present in the following releases:
SPARC Platform
- Solaris 10 without patch 126363-08
- OpenSolaris based upon builds snv_37 through snv_125
x86 Platform
- Solaris 10 without patch 126364-08
- OpenSolaris based upon builds snv_37 through snv_125
Note 1: Solaris 8, Solaris 9 and releases of Solaris 10 prior
to
Solaris 10 11/06 do not include Solaris Trusted Extensions and so do
not have this weakness.
Note 2: This issue only impacts Solaris 10 and OpenSolaris
systems
which have installed and configured Solaris Trusted Extensions. To
determine if a system is configured with Trusted Extensions, the
following command can be run in the global zone:
$ svcs /system/labeld
STATE STIME FMRI
online 10:02:34 svc:/system/labeld:default
If the state is disabled or if the labeld service is not listed,
then the system is not configured to use Trusted Extensions.
3. Symptoms
There are no predictable symptoms that would indicate the described
weakness has been exploited to gain elevated privileges.
4. Workaround
To work around the described issue for the Xorg(1) server, the
XTEST extension
may be disabled by adding the following lines to xorg.conf(4) file:
Section "Extensions"
Option "XTEST" "disable"
EndSection
4. Resolution
This issue is addressed in the following releases:
SPARC Platform
- Solaris 10 with patch 126363-08 or later
- OpenSolaris based upon builds snv_126 or later
x86 Platform
- Solaris 10 with patch 126364-08 or later
- OpenSolaris based upon builds snv_126 or later
