  <title>X.org, XFree86: Integer and stack overflows in libXpm</title>
  <synopsis>
    libXpm, the X Pixmap library that is a part of the X Window System,
    contains multiple stack and integer overflows that may allow a
    carefully-crafted XPM file to crash applications linked against libXpm,
    potentially allowing the execution of arbitrary code.

    XFree86 and X.org are both implementations of the X Window System.

    <p>
    Chris Evans has discovered multiple integer and stack overflow
    vulnerabilities in the X Pixmap library, libXpm, which is a part of the
    X Window System. These overflows can be exploited by the execution of a
    malicious XPM file, which can crash applications that are dependent on
    libXpm.
    </p>
  </description>
  <impact type="normal">
    <p>
    A carefully-crafted XPM file could crash applications that are linked
    against libXpm, potentially allowing the execution of arbitrary code
    with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All X.org users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=x11-base/xorg-x11-6.7.0-r2"
    # emerge "&gt;=x11-base/xorg-x11-6.7.0-r2"</code>
    <p>
    All XFree86 users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=x11-base/xfree-4.3.0-r7"
    # emerge "&gt;=x11-base/xfree-4.3.0-r7"</code>
    <p>
    Note: Usage of XFree86 is deprecated on the AMD64, HPPA, IA64, MIPS,
    PPC and SPARC architectures: XFree86 users on those architectures
    should switch to X.org rather than upgrading XFree86.
