Security Vulnerability in the Sun Ray Server Software Authentication
Manager May Allow a Denial of Service (DoS)
_________________________________________________________________
Category : Security
Release Phase : Resolved
Bug Id : 6838464
Product : Sun Ray Server Software 4.0
Sun Ray Server Software 4.1
Date of Resolved Release : 09-Dec-2009
Security Vulnerability in the Sun Ray Server Software Authentication Manager
May Allow a Denial of Service (DoS)
1. Impact
A security vulnerability in the Sun Ray Server Software Authentication
Manager may allow a remote unprivileged user to cause a Denial of
Service (DoS) to Sun Ray services or to run arbitrary code with root
privileges.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Sun Ray Server Software 4.0 (for Solaris 10) without patch
127553-07
* Sun Ray Server Software 4.1 (for Solaris 10) without patch
139548-03
x86 Platform
* Sun Ray Server Software 4.0 (for Solaris 10) without patch
127554-07
* Sun Ray Server Software 4.1 (for Solaris 10) without patch
139549-03
Linux
* Sun Ray Server Software 4.0 (for RHEL AS 4, SLES 9) without patch
127555-07
* Sun Ray Server Software 4.1 (for RHEL 5, SLES 10) without patch
139550-03
To determine if Authentication Manager is running, the following
command can be run:
$ ps -ef | grep utauth
root 3910 3909 0 Jul 31 ? 434:01 /etc/opt/SUNWut/jre/bin/java -client
auth.utauthd.utauthd
If no Java process with '-client auth.utauthd.utauthd' parameters is
listed, then Sun Ray Authentication Manager is not running.
Alternatively, If utauthd(1M) has crashed, running the utgstatus(1M)
tool will report an error:
$ /opt/SUNWut/sbin/utgstatus
Error: Could not get gstatus information from server <hostname>
3. Symptoms
Sun Ray DTUs will show a 26D OSD icon if the Sun Ray Authentication
Manager is no longer running.
There are no reliable symptoms which would indicate that this issue
has been exploited to execute arbitrary code without crashing the Sun
Ray Authentication Manager.
Commands such as the following can be used to determine if the Sun Ray
Authentication Manager is no longer running on the server:
$ ps -ef | grep utauth
root 3910 3909 0 Jul 31 ? 434:01 /etc/opt/SUNWut/jre/bin/java -client auth.u
tauthd.utauthd
If no java process with '-client auth.utauthd.utauthd' parameters is
listed, then the Authentication Manager is not running.
Alternatively, If utauthd(1M) has crashed, running the utgstatus(1M)
tool will report an error:
$ /opt/SUNWut/sbin/utgstatus
Error: Could not get gstatus information from server <hostname>
4. Workaround
There is no workaround for this issue. Please see the Resolution
section below.
5. Resolution
