    Synopsis
    ========

    Several format string vulnerabilities are present in the Neon library
    included in OpenOffice.org, allowing remote execution of arbitrary
    code when connected to an untrusted WebDAV server.

    Background
    ==========

    OpenOffice.org is an office productivity suite, including word
    processing, spreadsheets, presentations, drawings, data charting,
    formula editing, and file conversion facilities.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 app-office/openoffice <= 1.1.1 >= 1.1.1-r1
      2 app-office/openoffice <= 1.0.3-r1 >= 1.0.3-r2
      3 app-office/openoffice <= 1.1.0-r3 >= 1.1.0-r4
      4 app-office/openoffice-ximian <= 1.1.51 >= 1.1.51-r1
      5 app-office/openoffice-ximian-bin <= 1.1.52 1.1.51-r1
      6 app-office/openoffice-bin <= 1.1.1 1.1.51-r1
        -------------------------------------------------------------------
         # Package 1 [app-office/openoffice] only applies to X86 users.
         # Package 2 [app-office/openoffice] only applies to PPC users.
         # Package 3 [app-office/openoffice] only applies to SPARC users.

      NOTE: All packages listed without architecture tags apply to all
            architectures...

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

    OpenOffice.org includes code from the Neon library in functions related
    to publication on WebDAV servers. This library is vulnerable to several
    format string attacks.

    Impact
    ======

    If you use the WebDAV publication and connect to a malicious WebDAV
    server, this server can exploit these vulnerabilities to execute
    arbitrary code with the rights of the user running OpenOffice.org.

    Workaround
    ==========

    As a workaround, you should not use the WebDAV publication facilities.

    Resolution
    ==========

    There is no binary version including the fix yet. All users of the
    openoffice-bin and ximian-openoffice-bin packages making use of the
    WebDAV publication functions should upgrade to the latest version of
    the corresponding source-based package.

    openoffice users on the x86 architecture should:

        # emerge sync

        # emerge -pv ">=app-office/openoffice-1.1.1-r1"
        # emerge ">=app-office/openoffice-1.1.1-r1"

    openoffice users on the sparc architecture should:

        # emerge sync

        # emerge -pv ">=app-office/openoffice-1.1.0-r3"
        # emerge ">=app-office/openoffice-1.1.0-r3"

    openoffice users on the ppc architecture should:

        # emerge sync

        # emerge -pv ">=app-office/openoffice-1.0.3-r1"
        # emerge ">=app-office/openoffice-1.0.3-r1"

    openoffice-ximian users should:

        # emerge sync

        # emerge -pv ">=app-office/openoffice-ximian-1.1.51-r1"
        # emerge ">=app-office/openoffice-ximian-1.1.51-r1"
