<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 ">=dev-libs/elfutils-0.108"</code>
</resolution>
