1.  Bulletins Topics

    Sun announces the release of patches for Solaris(tm) 7, 2.6, 2.5.1,
    2.5, 2.4, and 2.3 (SunOS(tm) 5.7, 5.6, 5.5.1, 5.5, 5.4 and 5.3), which
    relate to a vulnerability with snoop.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running SunOS 5.7, 5.6, 5.5.1, 5.5, 5.4, and 5.3.

2.  Who is Affected
        
    Vulnerable:     SunOS 5.7, 5.7_x86, 5.6, 5.6_x86, 5.5.1, 5.5.1_x86,
                              5.5, 5.5_x86, 5.4, 5.4_x86, and 5.3.

    Not vulnerable: All other supported versions of SunOS.

3.  Understanding the Vulnerability

    The snoop program captures packets from the network and displays their
    contents. A buffer overflow vulnerability has been discovered which may
    be exploited by a remote attacker to execute arbitrary instructions
    and gain root access. The buffer overflow occurs when snoop analyzes
    certain types of large requests to the rquotad rpc service.

    The following patches are available in relation to the above problem.
