PLATFORM: SPARC Platform Solaris 7 without patch 107337-04 Solaris 8 without patch 111400-03 Solaris 9 without patch 114636-03 x86 Platform Solaris 7 without patch 107339-04 Solaris 8 without patch 111401-03 Solaris 9 without patch 114637-03 Note: Solaris 10 is not affected by this issue. DAMAGE: May allow local unprivileged users the ability to modify any file on the system. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. This could result in a Denial of Service ASSESSMENT: (DoS), possibly elevated privileges, and a local user could gain root privileges. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/p-143.shtml ORIGINAL BULLETIN: Sun Alert ID: 57706 http://www.sunsolve.sun.com/search/document.do?assetkey=1 -26-57706-1&searchclause=%22category:security%22%20%22 availability,%20security%22 CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2004-0481 ______________________________________________________________________________ [***** Start Sun Alert ID: 57706 *****] Sun(sm) Alert Notification Sun Alert ID: 57706 Synopsis: Security Vulnerability in the kcms_configure(1) Command May Allow Local Users the Ability to Modify Any File on the System Category: Security Product: Solaris BugIDs: 5040882 Avoidance: Workaround, Patch State: Resolved Date Released: 18-Feb-2005 Date Closed: 18-Feb-2005 Date Modified: 1. Impact A security vulnerability in the kcms_configure(1) command may allow local unprivileged users the ability to modify any file on the system. This can result in a Denial of Service (DoS) or possibly elevated privileges. Note: kcms_configure is part of the Kodak Color Management System (KCMS) which configures an X11 window system for use with the KCMS library. This issue is described in CAN-2004-0481 (see: http://cve.mitre.org/cgi-bin/ cvename.cgi?name=CAN-2004-0481) Sun acknowledges with thanks, iDEFENSE (http://www.idefense.com), for bringing this issue to our attention. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Solaris 7 without patch 107337-04 * Solaris 8 without patch 111400-03 * Solaris 9 without patch 114636-03 x86 Platform * Solaris 7 without patch 107339-04 * Solaris 8 without patch 111401-03 * Solaris 9 without patch 114637-03 Note: Solaris 10 is 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 If KCMS is not being used, the setuid(2) permissions on the kcms_configure(1) binary could be removed by running the following command as the root (uid 0) user: # chmod u-s /usr/openwin/bin/kcms_configure The KCMS packages below could also be removed by using the pkgrm(1M) command as root user: 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 For example: # pkgrm SUNWkcslx SUNWkcspf SUNWkcspg SUNWkcspx SUNWkcsrl SUNWkcsrr \ SUNWkcsrt SUNWkcsrx SUNWckcsr SUNWdkcsr SUNWekcsr SUNWfkcsr SUNWhkcsr \ SUNWikcsr SUNWjkcsr SUNWkkcsr SUNWskcsr 5.
