  <title>AMD64 x86 emulation base libraries: Buffer overflow</title>
  <synopsis>
    The x86 emulation base libraries for AMD64 contain a vulnerable version of
    zlib which could potentially lead to execution of arbitrary code.

    <package name="app-emulation/emul-linux-x86-baselibs" auto="yes" arch="amd64">

    <p>
    The x86 emulation base libraries for AMD64 emulate the x86 (32-bit)
    architecture on the AMD64 (64-bit) architecture.
    </p>
  </background>
  <description>
    <p>
    Earlier versions of emul-linux-x86-baselibs contain a vulnerable
    version of zlib, which may lead to a buffer overflow.
    </p>
  </description>
  <impact type="high">
    <p>
    By creating a specially crafted compressed data stream, attackers can
    overwrite data structures for applications that use the x86 emulation
    base libraries for AMD64, resulting in a Denial of Service and
    potentially arbitrary code execution.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All AMD64 x86 emulation base libraries users should upgrade to the
    latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose app-emulation/emul-linux-x86-baselibs</code>
  </resolution>
