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:
