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
   [1]http://www.kb.cert.org/vuls/id/850785) and the Entercept Security
   Alert at: [2]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
     * Solaris 7
     * Solaris 8
     * Solaris 9 without patch 114636-01
       
   Intel
     * Solaris 2.6
     * Solaris 7
     * Solaris 8
     * 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.
   
   SOLUTION SUMMARY:
   
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_se
rver

   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 <pid of inetd from above ps output>

   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
