    Synopsis
    ========

    Sylpheed and Sylpheed-claws contain a vulnerability that can be
    triggered when displaying messages with specially crafted attachments.

    Background
    ==========

    Sylpheed is a lightweight email client and newsreader. Sylpheed-claws
    is a 'bleeding edge' version of Sylpheed.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 mail-client/sylpheed < 1.0.4 >= 1.0.4
      2 mail-client/sylpheed-claws < 1.0.4 >= 1.0.4
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

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

    Sylpheed and Sylpheed-claws fail to properly handle messages containing
    attachments with MIME-encoded filenames.

    Impact
    ======

    An attacker can send a malicious email message which, when displayed,
    would cause the program to crash, potentially allowing the execution of
    arbitrary code with the privileges of the user running the software.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Sylpheed users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-1.0.4"

    All Sylpheed-claws users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.4"
