Sun(sm) Alert Notification
     * Sun Alert ID: 102728
     * Synopsis: Security Vulnerability in the kcms_calibrate(1) Command
     * Category: Security
     * Product: Solaris 9 Operating System, Solaris 8 Operating System
     * BugIDs: 6272418
     * Avoidance: Patch, Workaround
     * State: Resolved
     * Date Released: 22-Jan-2007
     * Date Closed: 22-Jan-2007
     * Date Modified: 

1. Impact

   A security vulnerability in the kcms_calibrate(1) command may allow
   local unprivileged users to execute arbitrary commands with root
   privileges.

   Sun acknowledges, with thanks, Cees-Bart Breunesse of the University
   of Nijmegen for bringing this issue to our attention.

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * Solaris 8 without patch 111400-04
     * Solaris 9 without patch 114636-04

   x86 Platform
     * Solaris 8 without patch 111401-04
     * Solaris 9 without patch 114637-04

   Note: Solaris 10 is not affected by this issue since the Kodak Color
   Management System (KCMS) no longer ships in Solaris 10 and later.

3. Symptoms

   There are no predictable symptoms that would indicate the described
   issue has been exploited to execute arbitrary code on a system. 

4. Relief/Workaround

   To prevent this issue from occurring until the patches listed in
   section 5 can be applied, the set-user-ID bit can be removed from the
   kcms_calibrate(1) binary using the following command as the root (uid
   0) user:
    # chmod u-s /usr/openwin/bin/kcms_calibrate

   Alternatively if the Kodak Color Management System (KCMS) utilities
   are not being used the following packages can be removed from the
   system using pkgrm(1M):

   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

   The following command uses pkgrm(1) as the root user to remove all of
   the above packages:
    # pkgrm SUNWkcslx SUNWkcspf SUNWkcspg SUNWkcspx SUNWkcsrl SUNWkcsrr \
    SUNWkcsrt SUNWkcsrx SUNWckcsr SUNWdkcsr SUNWekcsr SUNWfkcsr SUNWhkcsr \
    SUNWikcsr SUNWjkcsr SUNWkkcsr SUNWskcsr


5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform
     * Solaris 8 with patch 111400-04 or later
     * Solaris 9 with patch 114636-04 or later

   x86 Platform
     * Solaris 8 with patch 111401-04 or later
     * Solaris 9 with patch 114637-04 or later
