    Synopsis
    ========

    enscript suffers from vulnerabilities and design flaws, potentially
    resulting in the execution of arbitrary code.

    Background
    ==========

    enscript is a powerful ASCII to PostScript file converter.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 app-text/enscript < 1.6.3-r3 >= 1.6.3-r3

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

    Erik Sjolund discovered several issues in enscript: it suffers from
    several buffer overflows (CAN-2004-1186), quotes and shell escape
    characters are insufficiently sanitized in filenames (CAN-2004-1185),
    and it supported taking input from an arbitrary command pipe, with
    unwanted side effects (CAN-2004-1184).

    Impact
    ======

    An attacker could design malicious files or input data which, once
    feeded into enscript, would trigger the execution of arbitrary code
    with the rights of the user running enscript.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All enscript users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.3-r3"
