1.  Bulletins Topics

    Sun announces the release of patches for Solaris(tm) 8, 7, and
    2.6 (SunOS(tm) 5.8, 5.7, and 5.6) which relate to an in.lpd
    vulnerability reported in CERT CA-2001-15.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running SunOS 5.8, 5.7, and 5.6 which
    use in.lpd.

2.  Who is Affected

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

3.  Understanding the Vulnerability

    The in.lpd daemon is the BSD print protocol daemon.  The in.lpd
    daemon implements the network listening service for the BSD
    print protocol specified in RFC 1179.  The BSD print protocol
    provides a remote interface for systems to interact with a
    local spooling system. CERT Advisory CA-2001-15 describes a
    buffer overflow in the in.lpd daemon which may crash in.lpd or
    allow arbitrary code to be executed with elevated privileges
    on the victim system. The issue was discovered by ISS X-Force
    who published an advisory at:

    http://xforce.iss.net/alerts/advise80.php

    CERT Advisory CA-2001-15 is available from:

    http://www.cert.org/advisories/CA-2001-15.html
