Severity: Normal Title: Binutils, elfutils: Buffer overflow Date: June 01, 2005 Bugs: #91398, #91817 ID: 200506-01

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 the Gentoo Security Website:

Concerns? =========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
