       (HID) Class Driver for Solaris
     * Category: Security
     * Product: Solaris 9 Operating System, Solaris 10 Operating System,
       Solaris 8 Operating System
     * BugIDs: 6414967
     * Avoidance: Patch

1. Impact

   A security vulnerability in the Human Interface Device (HID) class
   driver for Solaris 8, 9 and 10 may allow a local unprivileged user to
   panic the system, causing a Denial of Service (DoS).

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * Solaris 8 without patch 109896-35
     * Solaris 9 without patch 115553-28
     * Solaris 10 without patch 125123-01

   x86 Platform
     * Solaris 9 without patch 115554-24
     * Solaris 10 without patch 125124-01

   Notes:
    1. Solaris 8 on the x86 platform is not affected by this issue.
    2. Systems are only impacted by this issue if the HID module is
       loaded. This happens as soon as you plugin a USB HID class device
       to the host. USB keyboard, mouse, etc fall into this category.

   To determine if the HID module is loaded, the following command can be
   run:
    $ modinfo | grep hid
    84  138cc18   36d8  54   1  hid (USB HID Client Driver 1.36)
    85  138f938   32e8   -   1  hidparser (HID PARSER 1.13)

3. Symptoms

   A system panic due to this issue will contain a stack trace similar to
   the following:
    freemsg+0x46()
    hid_qreply_merror+0x44()
    hid_wput+0x19f()
    putnext+0x31a()
    usbms_wput+0xc3()
    putnext+0x31a()
    consmslwserv+0x3d()
    runservice+0x62()
    queue_service+0x5b()
    stream_service+0xe8()
    taskq_d_thread+0xe8()
    thread_start+8() 

4. Relief/Workaround

   There is no workaround for this issue. Please see the Resolution
   section below.

5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform
     * Solaris 8 with patch 109896-35 or later
     * Solaris 9 with patch 115553-28 or later
