1.  Background

    The Berkeley Internet Name Domain (BIND) is an implementation of the
    Domain Name System (DNS).

    CERT Advisory CA-98.05 describes three vulnerabilities in certain
    versions of BIND. The first vulnerability, Inverse Query Buffer Overrun,
    can be exploited by a remote attacker to gain root access to a DNS
    name server. The second vulnerability, Denial-of-Service Vulnerabilities,
    is concerned with buffer overflows that can be exploited to corrupt
    DNS record data or crash the DNS server. SunOS(tm) and Solaris(tm) are
    not vulnerable to third vulnerability described in the CERT advisory.
    For more information about the vulnerabilities, please see the
    CERT advisory at:

        http://www.cert.org/ftp/cert_advisories/CA-98.05.bind_problems

    A vulnerability has also been discovered in SunOS and Solaris's
    implementation of BIND with their use of temporary files. This vulnerability
    can be exploited to overwrite arbitrary files.

2.  Affected Supported Versions

    Solaris(tm) versions:   2.6, 2.6_x86, 2.5.1, 2.5.1_x86, 2.5, 2.5_x86,
                            2.4, 2.4_x86 and 2.3

    SunOS(tm) versions:     4.1.4 and 4.1.3_U1

3.  Recommendations

    Sun recommends that you install the respective patches immediately on
    vulnerable systems including both DNS clients and servers.
