    Synopsis
    ========

    Several format string bugs and buffer overflows were discovered in
    metamail, potentially allowing execution of arbitrary code remotely.

    Background
    ==========

    Metamail is a program that decodes MIME encoded mail. It is therefore
    often automatically called when an email is received or read.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-mail/metamail < 2.7.45.3 >= 2.7.45.3

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

    Ulf Harnhammar found two format string bugs and two buffer overflow
    bugs in Metamail.

    Impact
    ======

    A remote attacker could send a malicious email message and execute
    arbitrary code with the rights of the process calling the Metamail
    program.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All users of Metamail should upgrade to the latest stable version:

        # emerge sync

        # emerge -pv ">=net-mail/metamail-2.7.45.3"
        # emerge ">=net-mail/metamail-2.7.45.3"
