===================================================================== CERT-Renater Note d'Information No. 2006/VULN416 _____________________________________________________________________ DATE : 01/08/2006 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running Sun N1 Grid Engine 6.0, Sun Grid Engine 5.3. ====================================================================== Sun(sm) Alert Notification * Sun Alert ID: 102322 * Synopsis: Security Vulnerability With Sun N1 Grid Engine Daemons * Category: Security * Product: Sun N1 Grid Engine 6, Sun Grid Engine 5.3 * BugIDs: 6398008, 6397987, 6365380 * Avoidance: Patch * State: Resolved * Date Released: 28-Jul-2006 * Date Closed: 28-Jul-2006 * Date Modified: 1. Impact A security vulnerability in the Sun N1 Grid Engine daemons may allow local unprivileged users to kill either the qmaster or execd process and shutdown the grid service, creating a Denial of Service (DoS) condition. In certain cases, buffer overflows may be exploited by unprivileged local users to gain elevated privileges. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Sun Grid Engine 5.3 (32-bit Solaris) * Sun Grid Engine 5.3 (64-bit Solaris) * Sun Grid Engine 5.3 (32-bit Solaris) NON-Solaris Package format * Sun Grid Engine 5.3 (64-bit Solaris) NON-Solaris Package format * N1 Grid Engine 6.0 (32-bit Solaris) without patch 123037-01 * N1 Grid Engine 6.0 (64-bit Solaris) without patch 123038-01 * N1 Grid Engine 6.0 (32-bit Solaris) NON-Solaris Package format without patch 123041-01 * N1 Grid Engine 6.0 (64-bit Solaris) NON-Solaris Package format without patch 123042-01 x86 Platform * Sun Grid Engine 5.3 * Sun Grid Engine 5.3 NON-Solaris Package format * N1 Grid Engine 6.0 without patch 123039-01 * N1 Grid Engine 6.0 NON-Solaris Package format without patch 123043-01 * N1 Grid Engine 6.0 (x64) without patch 123040-01 * N1 Grid Engine 6.0 (x64) NON-Solaris Package format without patch 123044-01 Linux * Sun Grid Engine 5.3 * N1 Grid Engine 6.0 without patch 123045-01 * N1 Grid Engine 6.0 (x64) without patch 123046-01 Windows * N1 Grid Engine 6.0 without patch 123052-01 HP-UX * N1 Grid Engine 6.0 without patch 123050-01 AIX * N1 Grid Engine 6.0 (for AIX 4.3) without patch 123047-01 * N1 Grid Engine 6.0 (for AIX 5.1) without patch 123048-01 Mac OS * N1 Grid Engine 6.0 without patch 123049-01 IRIX * N1 Grid Engine 6.0 (for IRIX 6.5) without patch 123051-01 3. Symptoms Should the described exploit occur, the 'qmaster' or 'execd' process is shut down and a core file will be created. To verify that your 'qmaster' or 'execd' process is not up and running, search in the process table with the 'ps' command for the process name "sge_qmaster" or "sge_execd". The following examples show a running qmaster: On Mac OS: $ ps ax | grep sge_qmaster 526 ?? S 12:44.97 /gridware/sge/bin/darwin/sge_qmaster all other platforms (including Windows, when using Windows Services for UNIX): $ ps -ef | grep sge_qmaster sgeadmin 13001 1 0 Apr 24 ? 19:17 /gridware/sge/bin/sol-sparc64/sge_qmaster If no 'qmaster' or 'execd' process was found in the process table the cluster may be affeced by this issue. 4. Relief/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 * N1 Grid Engine 6.0 (32-bit Solaris) with patch 123037-01 or later * N1 Grid Engine 6.0 (64-bit Solaris) with patch 123038-01 or later * N1 Grid Engine 6.0 (32-bit Solaris) NON-Solaris Package format with patch 123041-01 or later * N1 Grid Engine 6.0 (64-bit Solaris) NON-Solaris Package format with patch 123042-01 or later x86 Platform * N1 Grid Engine 6.0 with patch 123039-01 or later * N1 Grid Engine 6.0 NON-Solaris Package format with patch 123043-01 or later * N1 Grid Engine 6.0 (x64) with patch 123040-01 or later * N1 Grid Engine 6.0 (x64) NON-Solaris Package format with patch 123044-01 or later Linux * N1 Grid Engine 6.0 with patch 123045-01 or later * N1 Grid Engine 6.0 (x64) with patch 123046-01 or later Windows * N1 Grid Engine 6.0 with patch 123052-01 or later HP-UX * N1 Grid Engine 6.0 with patch 123050-01 or later AIX * N1 Grid Engine 6.0 (for AIX 4.3) with patch 123047-01 or later * N1 Grid Engine 6.0 (for AIX 5.1) with patch 123048-01 or later Mac OS * N1 Grid Engine 6.0 with patch 123049-01 or later IRIX * N1 Grid Engine 6.0 (for IRIX 6.5) with patch 123051-01 or later Note: Sun Grid Engine 5.3 will require an upgrade to N1 Grid Engine 6.0 with the appropriate patches to resolve this issue.
