-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0459 -- [Solaris] Installing a Kernel patch or certain Solaris Trusted Extensions patches may cause desktop login failures for systems configured with Solaris Trusted Extensions enabled 5 May 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Solaris 10 Operating System Publisher: Sun Microsystems Operating System: Solaris Impact: Denial of Service Access: Existing Account Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-237404-1 - --------------------------BEGIN INCLUDED TEXT-------------------- Solution Type: Sun Alert Solution 237404 : Installing a Kernel patch or certain Solaris Trusted Extensions patches may cause desktop login failures for systems configured with Solaris Trusted Extensions enabled Bug ID: 6691776, 6687697 Product Solaris 10 Operating System Date of Resolved Release: 02-May-2008 SA Document Body Installing a Kernel patch or certain Solaris Trusted Extensions patches may cause desktop login failures for systems configured with Solaris Trusted Extensions enabled 1. Impact Solaris 10 systems which have Solaris Trusted Extensions enabled which install kernel patch 127127-11, 127128-11 or certain Solaris Trusted Extensions patches may not be able to complete the login process. The desktop environment will fail to start. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform Case 1: Solaris 10 with patch 127127-11 (or later) and without patches 126363-03, 123611-03, and 126365-07 Case 2: Solaris 10 with patch 126365-04 (or later) and without patch 123611-03 x86 Platform Case 1: Solaris 10 with patch 127128-11 (or later) and without patches 126364-04, 123612-03, and 126366-07 Case 2: Solaris 10 with patch 126366-04 (or later) and without patch 123612-03 Note: Only systems configured with Solaris Trusted Extensions and matching one of the configurations of patches described above are impacted by this issue. To determine if a system is configured with Solaris Trusted Extensions, the following command can be run: $ svcs /system/labeld STATE STIME FMRI online 07:08:09 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 Installing the affected patches onto vulnerable systems with the patches as defined in section 2 above will cause the desktop environment to fail to start. For patches listed in Contributing Factors for Case 1 (either SPARC or x86): when the systems boot to multiuser mode, there will be a message indicating the Xserver has failed to start or the system will return a blank terminal only. For patches listed in Contributing Factors for Case 2 (either SPARC or x86): the user is able to commence the login dialog, the "Message Of The Day" and the Session Clearance Selection dialog, but after that the desktop stays frozen at the initial phase. 4. Workaround To avoid this issue, patches must be installed in the following order: For Case 1: SPARC Platform (for Solaris 10): 1. 126363-03 or later (SunOS 5.10: X Window System changes - Solaris Trusted Extensions) 2. 123611-03 or later (X11 6.6.2: Trusted Extensions patch) 3. 126365-07 or later (SunOS 5.10: CDE Desktop changes - Solaris Trusted Extensions) 4. 127127-11 SunOS 5.10: kernel patch x86 Platform (for Solaris 10): 1. 126364-04 or later (SunOS 5.10_x86: X Window System changes - Solaris Trusted Extensions) 2. 123612-03 or later (X11 6.6.2_x86: Trusted Extensions patch) 3. 126366-07 or later (SunOS 5.10_x86: CDE Desktop changes - Solaris Trusted Extensions) 4. 127128-11 SunOS 5.10_x86: kernel patch For Case 2: SPARC Platform (for Solaris 10): 1. 123611-03 or later (X11 6.6.2: Trusted Extensions patch) 2. 126365-04 or later (SunOS 5.10: CDE Desktop changes - Solaris Trusted Extensions x86 Platform (for Solaris 10): 1. 123612-03 or later (X11 6.6.2_x86: Trusted Extensions patch) 2. 126366-04 or later (SunOS 5.10_x86: CDE Desktop changes - Solaris Trusted Extensions) 5.
