Sun(sm) Alert Notification
      * Sun Alert ID: 102711
      * Synopsis: Security Vulnerabilities in OpenSSL May Lead to a Denial
        of Service (DoS) to Applications or Execution of Arbitrary Code
        With Elevated Privileges
      * Category: Security
      * Product: Solaris 10 Operating System
      * BugIDs: 6466370
      * Avoidance: Patch
      * State: Workaround
      * Date Released: 09-Nov-2006
      * Date Closed:
      * Date Modified: 13-Nov-2006, 26-Jun-2007

1. Impact

    Two security vulnerabilities in the OpenSSL product (see openssl(5))
    shipped with Solaris 10 may affect applications which make use of this
    product. Depending on the individual application, the first issue may
    allow a local or remote unprivileged user to execute arbitrary code
    with the privileges of the user running the application.

    The second issue may allow a remote user who controls a server to
    which an application connects to crash that application, causing a
    Denial of Service (DoS) condition.

    These issues are also referenced in the following documents:

    CVE-2006-4343 at
    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4343

    Sun wishes to acknowledge with thanks, Tavis Ormandy and Will Drewry
    (Google Security Team) for bringing these issues to our attention.

2. Contributing Factors

    These issues can occur in the following releases:

    SPARC Platform
      * Solaris 9
      * Solaris 10 without patch 121229-02 (libssl)
      * Solaris 10 with the Solaris Data Encryption Kit and without patch
        118562-13

    x86 Platform
      * Solaris 9
      * Solaris 10 without patch 121230-02 (libssl)
      * Solaris 10 with the Solaris Data Encryption Kit and without patch
        118563-13

    Note: Solaris 8 does not include the OpenSSL toolkit, and therefore is
    not vulnerable to this issue.

3. Symptoms

    There are no predictable symptoms which would indicate that the first
    issue mentioned above has been exploited to gain elevated privileges.

    If the second issue has been exploited, the affected application will
    no longer be available. Depending on the system configuration, core
    files may be created and application crashes may be recorded in system
    logs.

4. Relief/Workaround

    There is no workaround for these issues. Please see the Resolution
    section below.

5. Resolution

    These issues are addressed in the following releases:

    SPARC Platform
      * Solaris 10 with patch 121229-02 or later (libssl)
      * Solaris 10 with the Solaris Data Encryption Kit with patch
        118562-13 or later

    x86 Platform
      * Solaris 10 with patch 121230-02 or later (libssl)
      * Solaris 10 with the Solaris Data Encryption Kit with patch
        118563-13 or later

    Note: The Solaris Data Encryption Kit is optional, unbundled software
    which consists of the SUNWcry and SUNWcryr packages and is
    not installed by default on Solaris systems.

    A final resolution is pending completion.
