Message-ID: <200506011709.39513.jaervosz@gentoo.org> Date: Sun Jul 17 14:41:13 2005 From: jaervosz at gentoo.org (Sune Kloppenborg Jeppesen) Subject: [gentoo-announce] [ GLSA 200506-01 ] Binutils, elfutils: Buffer overflow - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200506-01 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 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: http://security.gentoo.org/glsa/glsa-200506-01.xml 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@...too.org or alternatively, you may file a bug at http://bugs.gentoo.org.
