    Synopsis
    ========

    Gnumeric is vulnerable to a heap overflow, possibly leading to the
    execution of arbitrary code.

    Background
    ==========

    The Gnumeric spreadsheet is a versatile application developed as part
    of the GNOME Office project. libpcre is a library providing functions
    for Perl-compatible regular expressions.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 app-office/gnumeric < 1.4.3-r2 >= 1.4.3-r2

    Description
    ===========

    Gnumeric contains a private copy of libpcre which is subject to an
    integer overflow leading to a heap overflow (see GLSA 200508-17).

    Impact
    ======

    An attacker could potentially exploit this vulnerability by tricking a
    user into opening a specially crafted spreadsheet, which could lead to
    the execution of arbitrary code with the privileges of the user running
    Gnumeric.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Gnumeric users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=app-office/gnumeric-1.4.3-r2"
