    Synopsis
    ========

    rxvt-unicode is vulnerable to a buffer overflow that could lead to the
    execution of arbitrary code.

    Background
    ==========

    rxvt-unicode is a clone of the well known terminal emulator rxvt.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 x11-terms/rxvt-unicode < 5.3 >= 5.3
                                                                     < 4.8

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

    Rob Holland of the Gentoo Linux Security Audit Team discovered that
    rxvt-unicode fails to properly check input length.

    Impact
    ======

    Successful exploitation would allow an attacker to execute arbitrary
    code with the permissions of the user running rxvt-unicode.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All rxvt-unicode users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=x11-terms/rxvt-unicode-5.3"
