PLATFORM: SPARC Platform Solaris 10 without patch 121012-01 x86 Platform Solaris 10 without patch 121013-01 DAMAGE: The vulnerability may allow an unauthorized local user to execute arbitrary code with elevated privileges. The traceroute(1M) utility in Solaris 10 is privilege aware and thus the only additional privilege available is PRIV_NET_RAWACCESS (see privileges(5)). This limits the impact by only allowing access to the network layer. SOLUTION: Apply the available security updates. ______________________________________________________________________________ VULNERABILITY The risk is LOW. An unauthorized local user may be able to ASSESSMENT: execute arbitrary code with elevated privileges. However, due to Solaris 10 privilege aware capabilities, the impact is limited. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/q-060.shtml ORIGINAL BULLETIN: http://www.sunsolve.sun.com/search/document.do?assetkey= 1-26-102060-1&searchclause=102060 CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2005-2071 ______________________________________________________________________________ [***** Start Sun Alert ID: 102060 *****] Document Audience: PUBLIC Document ID: 102060 Title: Security Vulnerabilities in the traceroute(1M) Utility may Allow Elevated Privileges Copyright Notice: Copyright © 2005 Sun Microsystems, Inc. All Rights Reserved Update Date: Wed Nov 23 00:00:00 MST 2005 Status Issued Description Top Sun(sm) Alert Notification * Sun Alert ID: 102060 * Synopsis: Security Vulnerabilities in the traceroute(1M) Utility may Allow Elevated Privileges * Category: Security * Product: Solaris 10 Operating System * BugIDs: 6290623, 6290611 * Avoidance: Patch, Workaround * State: Resolved * Date Released: 23-Nov-2005 * Date Closed: 23-Nov-2005 * Date Modified: 1. Impact Multiple security vulnerabilities in the traceroute(1M) utility may allow an unauthorized local user the ability to execute arbitrary code with elevated privileges. The traceroute(1M) utility in Solaris 10 is privilege aware and thus the only additional privilege available is PRIV_NET_RAWACCESS (see privileges(5)). This limits the impact by only allowing access to the network layer. These issues are described in the following document: * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2071 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Solaris 10 without patch 121012-01 x86 Platform * Solaris 10 without patch 121013-01 Note: Solaris 8 and Solaris 9 are not affected by this issue. 3. Symptoms There are no reliable symptoms that would indicate the described issue has been exploited. Solution Summary Top 4. Relief/Workaround To work around the described issue, the "set user ID bit" (suid) may be removed from the traceroute(1M) binary (or the binary may be removed altogether), which will render it unusable to non-root users. To remove the suid bit, run the following command as root user: # chmod u-s /usr/sbin/traceroute 5. Resolution This issue is addressed in the following releases: SPARC Platform * Solaris 10 with patch 121012-01 or later x86 Platform * Solaris 10 with patch 121013-01 or later This Sun Alert notification is being provided to you on an "AS IS" basis.
