    SA Document Body
    A Security Vulnerability May Allow Popup Windows to Appear Through the
    Solaris XScreenSaver Program

    1. Impact

    A security vulnerability in the Solaris XScreenSaver (see
    xscreensaver(1)) program may allow popup windows to appear through the
    lock screen and expose sensitive data. An example application affected
    by this issue is Thunderbird, which notifies users about new mail
    through popup windows.

    2. Contributing Factors

    This issue can occur in the following releases:
    SPARC Platform:
      * GNOME 2.0 (for Solaris 8)
      * GNOME 2.0 (for Solaris 9)
      * GNOME 2.0.2 (for Solaris 9)
      * Solaris 10 without patch 120094-22
      * OpenSolaris based upon builds snv_01 through snv_108

    x86 Platform
      * GNOME 2.0 (for Solaris 8)
      * GNOME 2.0 (for Solaris 9)
      * GNOME 2.0.2 (for Solaris 9)
      * Solaris 10 without patch 120095-22
      * Open Solaris based upon builds snv_01 through snv_108

    OpenSolaris distributions may include additional bug fixes above and
    beyond the build from which it was derived. The base build can be
    derived as follows:
    $ uname -v
    snv_101

    Systems are only impacted by this issue of they have the package
    SUNWxwsvr installed. To determine if this package is installed, the
    following command can be run:
    $ pkginfo SUNWxwsvr
    system    SUNWxwsvr XScreenSaver

    3. Symptoms

    There are no predictable symptoms that would indicate the described
    vulnerability has been exploited to reveal sensitive information.

    4. 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 10 with patch 120094-22 or later
      * Open Solaris based upon builds snv_109 or later

    x86 Platform:
      * Solaris 10 with patch 120095-22 or later
      * Open Solaris based upon builds snv_109 or later

    A final resolution is pending completion for GNOME 2.0 and 2.0.2.
