    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:
