    Synopsis
    ========

    xv contains multiple exploitable buffer overflows in the image handling
    code.

    Background
    ==========

    xv is a multi-format image manipulation utility.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-gfx/xv < 3.10a-r7 >= 3.10a-r7

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

    Multiple buffer overflow and integer handling vulnerabilities have been
    discovered in xv's image processing code. These vulnerabilities have
    been found in the xvbmp.c, xviris.c, xvpcx.c and xvpm.c source files.

    Impact
    ======

    An attacker might be able to embed malicious code into an image, which
    would lead to the execution of arbitrary code under the privileges of
    the user viewing the image.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All xv users should upgrade to the latest stable version:

        # emerge sync

        # emerge -pv ">=media-gfx/xv-3.10a-r7"
        # emerge ">=media-gfx/xv-3.10a-r7"
