Release Phase

Bug Id

Solaris 10 Operating System

Date of Resolved Release

A security vulnerability in Solaris Trusted Extensions due to missing libraries may allow privilege escalation:

1. Impact

A security vulnerability in Solaris Trusted Extensions due to libraries which were not delivered with the Trusted Extensions may allow a local privileged user to run arbitrary code with elevated privileges.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform
  • Solaris 10 without patch 143502-01
x86 Platform
  • Solaris 10 without patch 143503-01
Note 1: Solaris 8, 9 and OpenSolaris are not impacted by this issue. Releases prior to Solaris 10 11/06 do not include Solaris Trusted Extensions and therefore are not vulnerable to this issue.

Note 2: This issue only impacts systems that have Solaris Trusted Extensions installed and running. To determine if  a system is configured with Trusted Extensions and running on a host, execute the following command in the global zone:
    $ svcs labeld
online 16:19:20 svc:/system/labeld:default
If the state is "disabled" or if "/system/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 issue has been exploited to gain elevated privileges..

4. Workaround

There is no workaround for this issue. Please see the Resolution section below.

5. Resolution

This issue is addressed in the following releases:

SPARC Platform
  • Solaris 10 with patch 143502-01 or later
x86 Platform
  • Solaris 10 with patch 143503-01 or later
