    Synopsis
    ========

    XLI and Xloadimage contain a vulnerability which could potentially
    result in the execution of arbitrary code.

    Background
    ==========

    XLI and Xloadimage are X11 image manipulation utilities.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-gfx/xli < 1.17.0-r2 >= 1.17.0-r2
      2 media-gfx/xloadimage < 4.1-r4 >= 4.1-r4
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

    Description
    ===========

    When XLI or Xloadimage process an image, they create a new image object
    to contain the new image, copying the title from the old image to the
    newly created image. Ariel Berkman reported that the 'zoom', 'reduce',
    and 'rotate' functions use a fixed length buffer to contain the new
    title, which could be overwritten by the NIFF or XPM image processors.

    Impact
    ======

    A malicious user could craft a malicious XPM or NIFF file and entice a
    user to view it using XLI, or manipulate it using Xloadimage,
    potentially resulting in the execution of arbitrary code with the
    permissions of the user running XLI or Xloadimage.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All XLI users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-gfx/xli-1.17.0-r2"

    All Xloadimage users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-gfx/xloadimage-4.1-r4"
