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.
Background
==========
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.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/elfutils < 0.108 >= 0.108
2 sys-devel/binutils < 2.16-r1 *>= 2.14.90.0.8-r3
*>= 2.15.90.0.1.1-r5
*>= 2.15.90.0.3-r5
*>= 2.15.91.0.2-r2
*>= 2.15.92.0.2-r10
>= 2.16-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.

Description
===========
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.
Impact
======
Successful exploitation would require a user to access a specially
crafted binary file, resulting in the execution of arbitrary code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GNU Binutils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose sys-devel/binutils
All elfutils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.108"
Availability
============
This GLSA and any updates to it are available for viewing at
