Summary: Obsoleted by: 109327-24 SunOS 5.8_x86: libresolv.so.2, in.named and BIND9 patch

Date:  Aug/08/2008

Installation Requirements:

See Special Install Instructions                      
                      After installing this patch on an active boot environment, the system will be in a potentially inconsistent state until a reboot is performed.  Unless                      
                      otherwise specified in the Special Install Instructions below, it is normally safe to apply further patches prior to initiating the reboot due to the relatively small footprint of the patch utilities.  Normal operations must not be resumed until after the reboot is performed.                      
                      Use Single User Mode (run level S) when installing this patch on an active boot environment.  An alternative may be specified in the Special Install Instructions.

Patch Installation Instructions: 

--------------------------------
 
For Solaris 2.0-2.6 releases, refer to the Install.info file and/or
the README within the patch for instructions on using the generic
'installpatch' and 'backoutpatch' scripts provided with each patch.
 
For Solaris 7-10 releases, refer to the man pages for instructions
on using 'patchadd' and 'patchrm' scripts provided with Solaris.
Any other special or non-generic installation instructions should be
described below as special instructions.  The following example
installs a patch to a standalone machine:
 
       example# patchadd /var/spool/patch/104945-02
 
The following example removes a patch from a standalone system:
 
       example# patchrm 104945-02
 
For additional examples please see the appropriate man pages.

Special Install Instructions: 

-----------------------------
 
NOTE  1: To get the complete fix for 4324375 (rsh to machine with
         two interfaces on same subnet has problems with firewall),
         please also install the following patches:
 
         111328-02 (or greater)  /usr/lib/libsocket.so.1 patch
         108986-03 (or greater)  /usr/sbin/in.rshd patch
 
NOTE  2: To get complete fix for bug 4491688 (inet_network has some sloppy code
         and needs to be cleaned up) please also install the following patch:
 
         111328-05 (or greater)  libsocket patch
 
NOTE  3: Administrators MUST migrate their recursive BIND servers from BIND 8
         to BIND 9 to get relief for CR 6702096 (CERT VU#800113).  That is to
         say /usr/lib/dns/named must be used in place of /usr/sbin/in.named as
         detailed below.  The installation of this patch alone without migration
         offers no protection from the security vulnerabilities which are
         resolved by using BIND 9.  For further information regarding the
         security implications of running BIND 8 please refer to SunAlert 240048
         (previously 239392):
         http://sunsolve.sun.com/search/document.do?assetkey=1-66-240048-1
 
         BIND 9 is provided in /usr/lib/dns by patch on the Solaris 8 Operating
         Environment to enable customers to migrate from the older and insecure
         version of BIND 8 provided in /usr/sbin/in.named.
 
   +------------------------------------------------------------------------+
   |   NOTE: at this time we are aware of two issues which may occur        |
   |             following the installation of this patch:                  |
   |                                                                        |
   | 6728975 Fix for 6702096 causes named (9.3.5.P1) to use high CPU usage. |
   | 6726921 Bind 9.3.5-P1 breaks dns (too many open file descriptors)      |
   |                                                                        |
   | The version of BIND 9.3.5-P1 has been compiled with FD_SETSIZE set     |
   | to 8192 to prevent 6726921 from occurring,  if your BIND server does   |
   | still experience 6726921 then please let us know.                      |
   |                                                                        |
   | The issues documented above will be addressed in a later version of    |
   | BIND.                                                                  |
   |                                                                        |
