Impact Two Security Vulnerabilities in Solaris Trusted Extensions label daemon (labeld) may allow a local unprivileged user to stop Trusted Extensions services from running on a system. When this occurs, all existing Trusted Desktop sessions would hang and unprivileged users may not be able to log in to the affected trusted system. This creates a Denial of Service (DoS) condition. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Solaris 10 without patch 126448-04 x86 Platform * Solaris 10 without patch 126449-04 Note: Solaris 8 and Solaris 9 are not impacted by these issues. To determine if a system is configured with Trusted Extensions, the following command can be run: $ svcs /system/labeld STATE STIME FMRI online 07:08:09 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 Should the described issue occur, a Trusted Extensions service "svc:/system/labeld" would be in a "maintenance" state. To determine the state of the "labeld" service, the following command can be run: $ svcs /system/labeld STATE STIME FMRI maintenance 07:08:09 svc:/system/labeld:default 4. Relief/Workaround There is no workaround. Please see the Resolution section below. 5. Resolution This issue is addressed in the following releases: SPARC Platform * Solaris 10 with patch 126448-04 or later x86 Platform * Solaris 10 with patch 126449-04 or later This Sun Alert notification is being provided to you on an "AS IS" basis.
