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"
