Sun estimates that the release of a patch for Solaris 2.3 (SunOS 5.3) that relates to the same vulnerability will be available within 12 weeks of the date of this bulletin. Sun strongly recommends that you install the patches listed in section 4 immediately on systems running SunOS 5.6, 5.6_x86, 5.5.1, 5.5, and 5.4 which use rpc.nisd. 2. Who is Affected Vulnerable: SunOS 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 on systems which are NIS+ servers. Not vulnerable: All other supported versions of SunOS. 3. Understanding the Vulnerability The rpc.nisd daemon is an RPC service that implements the NIS+ service. This daemon must be running on all machines which serve a portion of the NIS+ namespace. A buffer overflow has been discovered in rpc.nisd which could be exploited to gain root access and execute arbitrary commands. 4.
