Sun(sm) Alert Notification
      * Sun Alert ID: 102040
      * Synopsis: A Security Vulnerability in the "libike" Library May
        Affect the in.iked(1M) Daemon
      * Category: Security
      * Product: Solaris 9 Operating System, Solaris 10 Operating System
      * BugIDs: 6317027
      * Avoidance: T-Patch
      * State: Workaround
      * Date Released: 14-Nov-2005
      * Date Closed:
      * Date Modified:

1. Impact

    A remote privileged user may be able to attempt an IKE exchange using
    a malformed payload, which could cause the in.iked(1M) process to
    crash, causing a Denial of Service (DoS) of IPSec key management
    services.

    This issue is revealed by the test suite which is described in NISCC
    vulnerability #273756, which is available at
    http://www.uniras.gov.uk/niscc/docs/br-20051114-01013.html?lang=en

2. Contributing Factors

    This issue can occur in the following releases:

    SPARC Platform
      * Solaris 9
      * Solaris 10

    x86 Platform
      * Solaris 9
      * Solaris 10

    Notes:
     1. Solaris 8 is not affected by this issue.
     2. The described issue only affects systems running the IKE (Internet
        Key Exchange) daemon in.iked(1M).

    To determine if the in.iked(1M) is running on a system, the following
    command can be run:
     # pgrep -l in.iked
     368 in.iked

3. Symptoms

    If this issue has been exploited, the IKE daemon would no longer be
    running. To determine that the IKE (in.iked(1M)) daemon is NOT running
    on a system, the following command can be run:
     $ pgrep in.iked || echo "in.iked not running"

4. Relief/Workaround

    Preliminary T-patches are available for the following releases from
    http://sunsolve.sun.com/tpatches:

    SPARC Platform
      * Solaris 9 T-patch T113451-10
