1.  Bulletins Topics

    Sun announces the release of patches for Solaris 2.5.1, 2.5, 2.4, 2.3,
    (SunOS 5.5.1, 5.5, 5.4, 5.3), SunOS 4.1.4, and 4.1.3_U1, which relate
    to vulnerabilities in ftpd/rlogin.

    Sun strongly recommends that you install the patches listed in section 4
    immediately on systems running SunOS 5.5.1, 5.5, 5.4, 5.3, 4.1.4, and
    4.1.3_U1.

2.  Who is Affected

    Vulnerable:  SunOS versions 5.5.1, 5.5.1_x86, 5.5, 5.5_x86,
                                5.4, 5.4_x86, 5.3, 4.1.4, and 4.1.3_U1

    The vulnerability is fixed in Solaris 2.6.

3.  Understanding the Vulnerability

    The daemon in.ftpd is the Internet File Transfer Protocol (FTP) server
    process and the daemon in.rlogind is the rlogin server process. This
    vulnerability, if exploited, allows an unprivileged user to connect from
    an ftp server's data port to a rlogin server on a host that trusts the host
    that the ftp server resides on. If exploited, attackers may execute
    arbitrary commands on the attacked host.

4.  List of Patches

    The vulnerability in ftpd/rlogind is fixed by the following patches:

    OS version          Patch ID
