    Synopsis
    ========

    Sylpheed and Sylpheed-Claws contain a buffer overflow vulnerability
    which may lead to the execution of arbitrary code.

    Background
    ==========

    Sylpheed is a lightweight email client and newsreader. Sylpheed-Claws
    is a 'bleeding edge' version of Sylpheed. They both support the import
    of address books in LDIF (Lightweight Directory Interchange Format).

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 mail-client/sylpheed < 2.0.4 >= 2.0.4
      2 mail-client/sylpheed-claws < 1.0.5-r1 >= 1.0.5-r1
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

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

    Colin Leroy reported buffer overflow vulnerabilities in Sylpheed and
    Sylpheed-Claws. The LDIF importer uses a fixed length buffer to store
    data of variable length. Two similar problems exist also in the Mutt
    and Pine addressbook importers of Sylpheed-Claws.

    Impact
    ======

    By convincing a user to import a specially-crafted LDIF file into the
    address book, a remote attacker could 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-2.0.4"

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

        # emerge --sync
        # emerge --ask --oneshot --verbose
    ">=mail-client/sylpheed-claws-1.0.5-r1"
