  <title>Binutils, elfutils: Buffer overflow</title>
  <synopsis>
    Various utilities from the GNU Binutils and elfutils packages are
    vulnerable to a heap based buffer overflow, potentially resulting in the
    execution of arbitrary code.

    <p>
    The GNU Binutils are a collection of tools to create, modify and
    analyse binary files. Many of the files use BFD, the Binary File
    Descriptor library, to do low-level manipulation. Elfutils provides a
    library and utilities to access, modify and analyse ELF objects.
    </p>

  <description>
    <p>
    Tavis Ormandy and Ned Ludd of the Gentoo Linux Security Audit Team
    discovered an integer overflow in the BFD library and elfutils,
    resulting in a heap based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful exploitation would require a user to access a specially
    crafted binary file, resulting in the execution of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GNU Binutils users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose sys-devel/binutils</code>
    <p>
    All elfutils users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/elfutils-0.108"</code>
  </resolution>
