__________________________________________________________ The U.S. Department of Energy Computer Incident Advisory Capability ___ __ __ _ ___ / | /_\ / \___ __|__ / \ \___ __________________________________________________________ INFORMATION BULLETIN Sun kcms_server Daemon Vulnerability [Sun Alert ID: 50104] February 4, 2004 18:00 GMT Number O-069 [REVISED 11 Feb 2004] [REVISED 26 FEB 2004] ______________________________________________________________________________ PROBLEM: The Solaris kcms_server(1) daemon is part of the Kodak Color Management System (KCMS), an API and libraries to create and manage profiles that can describe and control the color performance of digital color images on desktop computers and associated peripherals. The daemon does not adequately validate the filename arguments in the KCMS profile files. PLATFORM: SPARC and x86 platforms Solaris 2.6 without patch 107336-02 Solaris 7 without patch 107337-03 Solaris 8 without patch 111400-02 Solaris 9 without patch 114636-01 DAMAGE: A local or remote unprivileged user may be able to view root privileged files. SOLUTION: Apply the appropriate Sun patches. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. The kcms_server(1) daemon is enabled by ASSESSMENT: default in the inetd.conf(4) file and runs with root privileges. A local or remote attacker could view root privileged files. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/o-069.shtml ORIGINAL BULLETIN: http://sunsolve.sun.com/search/document.do?assetkey=1-26-50104-1 ______________________________________________________________________________ REVISION HISTORY: 02/11/04 - revised to reflect Sun Alert ID: 50104. 02/26/04 - revised to reflect changes to Sun Alert ID: 50104. [***** Start Sun Alert ID: 50104 *****] Sun(sm) Alert Notification Sun Alert ID: 50104 Synopsis: Security Issue with kcms_server Daemon Category: Security Product: Solaris BugIDs: 4774256 Avoidance: Workaround, Patch State: Resolved Date Released: 23-Jan-2003, 24-Feb-2004 Date Closed: 24-Feb-2004 Date Modified: 08-Aug-2003, 10-Feb-2004, 24-Feb-2004 1. Impact A local or remote unprivileged user may be able to view root privileged files due to a security vulnerability involving the Solaris kcms_server(1) daemon. The Solaris kcms_server(1) daemon is part of the Kodak Color Management System (KCMS), an API and libraries to create and manage profiles that can describe and control the color performance of digital color images on desktop computers and associated peripherals. The kcms_server(1) daemon is enabled by default in the inetd.conf(4) file. This issue is described in the CERT Vulnerability VU#850785 (see http://www.kb.cert.org /vuls/id/850785) and the Entercept Security Alert at: http://www.entercept.com/news/ uspr/01-22-03.asp. Sun acknowledges with thanks, Sinan Eren of the Entercept Ricochet Team, for bringing this issue to our attention. 2. Contributing Factors This issue can occur in the following releases: SPARC Solaris 2.6 without patch 107336-02 Solaris 7 without patch 107337-03 Solaris 8 without patch 111400-02 Solaris 9 without patch 114636-01 Intel Solaris 2.6 without patch 107338-02 Solaris 7 without patch 107339-03 Solaris 8 without patch 111401-02 Solaris 9 without patch 114637-01 3. Symptoms There are no reliable symptoms that would show the described issue has been exploited to gain access to view root privileged files. 4. Relief/Workaround The following workarounds can be implemented as the root user to prevent an exploit for this issue from succeeding: 1. Disable the kcms_server(1) daemon on all systems. a) Edit the "/etc/inetd.conf" file and comment out the following line by prepending the '#' symbol as follows. # 100221/1 tli rpc/tcp wait root /usr/openwin/bin/kcms_server kcms_server b) Instruct the inetd(1M) process to reread the newly modified "/etc/inetd.conf" file by sending it a hangup signal, SIGHUP: $ ps -ef | grep inetd $ kill -HUP 2. Remove the KCMS related packages using pkgrm(1) as the root user. The following are the KCMS packages: Core KCMS packages: application SUNWkcslx KCMS Runtime Library (64-bit) application SUNWkcspf KCMS Optional Profiles application SUNWkcspg KCMS Programmers Environment application SUNWkcspx KCMS Programmers Environment (64-bit) system SUNWkcsrl KCMS Runtime Library Support system SUNWkcsrr KCMS Runtime Profiles application SUNWkcsrt KCMS Runtime Environment application SUNWkcsrx KCMS Runtime Environment (64-bit) Translated KCMS packages: ALE SUNWckcsr Simplified Chinese (EUC) KCMS Runtime Environment application SUNWdkcsr German KCMS Runtime Environment application SUNWekcsr Spanish KCMS Runtime Environment application SUNWfkcsr French KCMS Runtime Environment ALE SUNWhkcsr Traditional Chinese (EUC) KCMS Runtime Environment application SUNWikcsr Italian KCMS Runtime Environment application SUNWjkcsr Japanese KCMS Runtime Environment ALE SUNWkkcsr Korean (EUC) KCMS Runtime Environment application SUNWskcsr Swedish KCMS Runtime Environment 5. Resolution This issue is addressed in the following releases: SPARC Platform Solaris 2.6 with patch 107336-02 or later Solaris 7 with patch 107337-03 or later Solaris 8 with patch 111400-02 or later Solaris 9 with patch 114636-01 or later x86 Platform Solaris 2.6 with patch 107338-02 or later Solaris 8 with patch 111401-02 or later Solaris 7 with patch 107339-03 or later Solaris 9 with patch 114637-01 or later A final resolution is pending completion for Solaris 8 x86.
