March 12, 1998 19:00 GMT                                          Number I-033
______________________________________________________________________________
PROBLEM:       Two vulnerabilities have been identified by Sun Microsystems.
               1) ndd commands can be used to set TCP/IP kernel parameters.
               2) The rpc.cmsd is a small database manager used for
                  appointments resource-scheduling data.
PLATFORM 1:    SunOS 5.6 and 5.6_x86. 
PLATFORM 2:    SunOS 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 running Openwindows.
               SunOS 5.5.1, 5.5.1_x86, 5.5, 5.5_x86, 5.4, and 5.4_x86 
               running CDE.
DAMAGE:        1) If exploited, attackers could set parameters to cause a
                  denial of service.
               2) If exploited, attackers could overwrite
                  arbitrary files and may gain root access.
SOLUTION:      Apply patches below.
______________________________________________________________________________
VULNERABILITY  Sun recommends that you install the patches listed immediately
ASSESSMENT:    for the affected systems.
