Synopsis
=======
Multiple vulnerabilities have been discovered in the GNU debugger, potentially allowing the execution of arbitrary code.
Background
=========
gdb is the GNU project's debugger, facilitating the analysis and debugging of applications. The BFD library provides a uniform method of accessing a variety of object file formats.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-devel/gdb < 6.3-r3 >= 6.3-r3
Description
==========
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered an integer overflow in the BFD library, resulting in a heap overflow. A review also showed that by default, gdb insecurely sources initialisation files from the working directory.
Impact
=====
Successful exploitation would result in the execution of arbitrary code on loading a specially crafted object file or the execution of arbitrary commands.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All gdb users should upgrade to the latest stable version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/gdb-6.3-r3"
Availability
===========
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200505-15.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@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
