Vulnerability Note VU#327281
Solaris rpc.yppasswdd does not adequately check input allowing users to execute arbitrary code
A remotely exploitable buffer overflow exists in the 'rpc.yppasswd' service on Solaris 2.6, 2.7, and 2.8.
Network Information Service (NIS) provides a simple network lookup service consisting of databases and processes. Its purpose is to provide information, that has to be known throughout the network, to all machines on the network. Information likely to be distributed by NIS might be login names and/or group information. A remotely exploitable buffer overflow exists in the 'rpc.yppasswd' service. This vulnerability could allow a remote intruder to execute arbitrary code with superuser privileges on an NIS master server. Note that only NIS master servers running the rpc.ypasswdd process are affected. For more information, please see this Sun Alert.
Remote intruders can execute arbitrary code with super user privileges on a NIS master server.
