1.  Bulletins Topics

    Sun announces the release of patches for Solaris(tm) 8, 7, 2.6,
    and 2.5.1 (SunOS(tm) 5.8, 5.7, 5.6, and 5.5.1) which relate to a
    buffer overflow in dtspcd.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running the CDE Subprocess control service,
    dtspcd, on SunOS 5.8, 5.7, 5.6, and 5.5.1.

2.  Who is Affected

    Vulnerable:                    SunOS 5.8, 5.8_x86, 5.7, 5.7_x86, 5.6,
                                   5.6_x86, 5.5.1, and 5.5.1_x86

3.  Understanding the Vulnerability

    The CDE Subprocess Control Service (dtspcd) daemon accepts requests
    from CDE clients to execute commands and launch applications on the
    local system running the dtspcd daemon.  The dtspcd daemon is spawned
    by the inetd daemon (see inetd(1M)) in response to a CDE client
    request. dtspcd is normally configured to run on port 6112/tcp with
    root privileges.

    A buffer overflow has been discovered in dtspcd which may be
    exploited by a local or a remote attacker to gain root access on the
    affected system.  Any system that does not run the CDE Subprocess
    Control service, dtspcd, is not vulnerable to this problem.  This
    issue was discovered by ISS X-Force who published an advisory at:

    http://xforce.iss.net/alerts/advise101.php

    CERT Advisory CA-2001-31 is available from:

    http://www.cert.org/advisories/CA-2001-31.html
