-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0763 -- [Solaris] A Security Vulnerability in picld(1M) May Allow a Denial of Service to System Monitoring and System Services 4 August 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Platform Information and Control Library daemon (picld) Publisher: Sun Microsystems Operating System: Solaris 10 Operating System Solaris 9 Operating System Solaris 8 Operating System OpenSolaris Impact: Denial of Service Access: Existing Account CVE Names: CVE-2008-3426 Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-239728-1 Revision History: August 4 2008: Added CVE information August 1 2008: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Solution Type: Sun Alert Solution 239728 : A Security Vulnerability in picld(1M) May Allow a Denial of Service to System Monitoring and System Services Bug ID: 6547926 Product Solaris 8 Operating System Solaris 9 Operating System Solaris 10 Operating System OpenSolaris Date of Resolved Release: 30-Jul-2008 SA Document Body A Security Vulnerability in picld(1M) May Allow a Denial of Service to System Monitoring and System Services 1. Impact Due to a security vulnerability in the Solaris Platform Information and Control Library daemon (picld(1M)), a local unprivileged user may be able to disable system monitoring and prevent system utilities (prtdiag(1M), prtpicl(1M), prtfru(1M)) from operating properly. This is a type of Denial of Service (DoS). 2. Contributing Factors This can occur in the following releases: SPARC Platform: * Solaris 8 (10/00 or later) without patch 112169-07 * Solaris 9 without patch 137400-01 * Solaris 10 without patch 138068-01 * OpenSolaris based upon builds snv_01 through snv_95 x86 Platform: * Solaris 9 without patch 137401-01 * Solaris 10 without patch 138069-01 * OpenSolaris based upon builds snv_01 through snv_95 Notes: 1. Solaris 8 on the x86 platform is not impacted by this issue 2. Only OpenSolaris installations including the affected binary below are impacted by this issue. /usr/lib/picl/picld 3. OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. The base build can be derived as follows: $ uname -a SunOS phys-node-1 5.11 snv_86 i86pc i386 i86pc 3. Symptoms If this issue has been exploited to cause a Denial of Service, invocations of prtpicl(1M), prtfru(1M) and prtdiag(1M) will not run to completion and will not display information that is normally seen. 4. Workaround There is no workaround that would prevent this issue from being exploited. If the issue has been exploited, it is possible to recover from the Denial of Service state by stopping and restarting picld(1M) by doing the following: For Solaris 10, issue the following command: # svcadm restart picl For Solaris 9 and 8, issue the following commands: # /etc/init.d/picld stop # /etc/init.d/picld start 5. Resolution This issue is addressed in the following releases: SPARC Platform: * Solaris 8 with patch 112169-07 or later * Solaris 9 with patch 137400-01 or later * Solaris 10 with patch 138068-01 or later * OpenSolaris based upon builds snv_96 or later x86 Platform: * Solaris 9 with patch 137401-01 or later * Solaris 10 with patch 138069-01 or later * OpenSolaris based upon builds snv_96 or later For more information on Security Sun Alerts, see Technical Instruction ID 213557.
