    This is OLD. Sun just hasn't fixed it yet. See the old CPIO Advisory on
    this: http://www.in.net/~jkatz/infosec/009.txt
    
    Casper Dik's "fix-modes" script from: ftp://ftp.wins.uva.nl/pub/solaris/
    is still valid.
    
    Take Care!

         **************** CPIO Security Notice ****************
         Issue Number 9: 971208
         Topic: Solaris /var Permission problems
         Platforms: Solaris 2.5.1, 2.6 / SPARC; possibly 2.5.
         **** Solaris /var permission problems ****
    
    Both Solaris 2.5.1 and Solaris 2.6 leave remarkably exploitable
    permissions on files and directories in /var after a default
    install. After patch installs, many of these highly insecure
    permissions still exist. Others may have noticed this behaviour,
    but no one at CPIO has yet seen it summarized or published.
    
    Careful examination of both operating systems (OK, running find(1)
    :) ) on sun4c, sun4m, and sun4u platforms yielded the following
    results. Solaris for x86 platforms may be similarly affected. After
    checking all machines with the same set of commands, we have found
    the following permission problems with these files:
    
    Solaris 2.5.1:
    	/var/adm/vold.log (mode 666, root:root)
    	/var/adm/spellhist (mode 666, bin:bin)
    	/var/adm/messages (mode 666, root:other) NOTE: this is the
    				first set of permissions on this
    				file. newsyslog fixes this during t
    				he archive process.
    	/var/adm/log/asppp.log (mode 666, root:root)
    	/var/news (directory, mode 777, bin:bin)
    	/var/log/syslog (mode 666, root:other) On initial install,
    				this is 664, but when rolled over,
    				becomes 666. Patch 104613 fixes this.
    	/var/log/sysidconf.log (mode 777, root:other)
    	/var/sadm/install/.pkg.lock (mode 666, root:root)
    	/var/spool/lp/fifos/FIFO (mode 666, lp:lp)
    	/var/lp/logs/lpsched (mode 666, root:root)
    	/var/lp/logs/lpNet (mode 666, root:root)
    	/var/preserve (directory, mode 777, bin:bin)
    	/var/spool/pkg (directory, mode 777, bin:bin)
    
    Solaris 2.6:
    	/var/adm/vold.log (mode 666, root:root)
    	/var/adm/spellhist (mode 666, bin:bin)
    	/var/log/sysidconf.log (mode 777, root:other)
    	/var/saf/_log (mode 666, root:root)
    	/var/dmi/db/1l.comp (mode 666, root:root)
    	/var/dmi/db/1l.tbl (mode 666, root:root)
    	/var/snmp/snmpdx.st  (mode 666, root:root)
    	/var/snmp/snmpdx.st.old (mode 666, root:root)
    
    
    PATCHES AND FIXES
    
    Some patches fix some problems-- patch 104613 fixes the
    /var/log/syslog problem on 2.5.1.
    
    In addition, Casper Dik has a program called "fix-modes" which is
    available from ftp://ftp.wins.uva.nl/pub/solaris/
    This fixes many of the descrepancies detailed here.
