- --------------------------BEGIN INCLUDED TEXT--------------------
Solution Type: Sun Alert
Solution 256748 : A Security Vulnerability in the Solaris
rpc.nisd(1M) Daemon may Cause a Denial of Service (DoS) Condition to a
NIS+ Server
Bug ID: 6466160
Product
Solaris 8 Operating System
Solaris 9 Operating System
Solaris 10 Operating System
OpenSolaris
Date of Resolved Release: 09-Jun-2009
SA Document Body
A security vulnerability in the Solaris rpc.nisd(1M) daemon may cause a
Denial of Service (DoS) condition to a NIS+ server:
1. Impact
A security vulnerability in the Solaris rpc.nisd(1M) daemon may allow
remote privileged users on certain NIS+ clients to cause a Denial of
Service (DoS) condition to a NIS+ server, preventing the server from
responding to all NIS+ client requests.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 8 without patch 128624-09
* Solaris 9 without patch 112960-65
* Solaris 10 without patch 140917-01
* OpenSolaris based upon builds snv_01 through snv_103
x86 Platform
* Solaris 8 without patch 128625-09
* Solaris 9 without patch 114242-50
* Solaris 10 without patch 140918-01
* OpenSolaris based upon builds snv_01 through snv_103
Note 1: OpenSolaris distributions may include additional bug fixes
above and beyond the build from which it was derived. To determine
the base build of OpenSolaris, the following command can be used:
$ uname -v
snv_86
Note 2: This issue only affects systems that are configured as NIS+
Master or Replica servers and have the rpc.nisd(1M) process running on
the system.
To determine if a system is a NIS+ Master or Replica server and if the
rpc.nisd(1M) service is running, the following command may be run:
On Solaris 10 and OpenSolaris systems:
$ svcs svc:/network/rpc/nisplus:default
STATE STIME FMRI
online Feb_17 svc:/network/rpc/nisplus:default
If the "state" field in the output is "disabled" the system is not
configured as a NIS+ Master or Replica server.
On Solaris 8 and 9 systems:
$ pgrep rpc.nisd || echo "This system is not a NIS+ server."
3. Symptoms
If the described issue occurs, NIS+ commands to lookup NIS+ data may
hang. For example, running the following command from the NIS+ server
machine may hang:
$ niscat hosts.org_dir
The stack trace of NIS+ server process rpc.nisd(1M) may be similar to
the following:
