Sun(sm) Alert Notification
     * Sun Alert ID: 102033
     * Synopsis: Vulnerabilities in lpsched(1M) May Allow an Unprivileged
       User to Remove System Files or Disable the LP Service
     * Category: Security
     * Product: Solaris 9 Operating System, Solaris 10 Operating System,
       Solaris 8 Operating System
     * BugIDs: 6314243, 6314245
     * Avoidance: Patch
     * State: Resolved
     * Date Released: 13-Jan-2006
     * Date Closed: 13-Jan-2006
     * Date Modified: 

1. Impact

   Security vulnerabilities in lpsched(1M) may allow a local unprivileged
   user the ability to delete any file or disable the LP print service on
   a system configured as a print server.

   Sun acknowledges, with thanks, Hiroshi Nakano of Ryukoku University
   for bringing these issues to our attention.

2. Contributing Factors

   These issues can occur in the following releases:

   SPARC Platform
     * Solaris 8 without patch 109320-17
     * Solaris 9 without patch 113329-16
     * Solaris 10 without patch 120467-03

   x86 Platform
     * Solaris 8 without patch 109321-17
     * Solaris 9 without patch 114980-17
     * Solaris 10 without patch 120468-03

   Note: Solaris 7 will not be evaluated regarding the potential impact
   of the issue described in this Sun Alert.

   This issue only affects systems which have been configured to act as
   print servers. To determine if the system has been configured as a
   print server, the following command can be used:
    $ ls /etc/lp/printers

   If there are files listed, then the host in question is a print
   server.

3. Symptoms

   There are a number of possible symptoms of this issue, including the
   modification/deletion of files owned by privileged users and the
   disabling of the main Solaris print daemon. In order to check whether
   the Solaris print daemon has been disabled on a print server, the
   following command can be run:
    % lpstat -r

   and will return either "scheduler is running" or "scheduler is not
   running." 

4. Relief/Workaround

   There is no workaround to these issues. Please see the Resolution
   section below.

5. Resolution

   These issues are addressed in the following releases:

   SPARC Platform
     * Solaris 8 with patch 109320-17 or later
     * Solaris 9 with patch 113329-16 or later
     * Solaris 10 with patch 120467-03 or later
