Solution 238414 : Security Vulnerability in Solaris 10 Service Tag
Registry May Allow Denial of Service
Bug ID: 6628819
Product
Sun Service Tag 1.0
Date of Resolved Release: 03-Jun-2008
SA Document Body
A security vulnerability in the Solaris 10 Service Tag Registry (see
below for details)
1. Impact
A security vulnerability in the Solaris 10 Service Tag Registry may
allow a local unprivileged user to fill the '/var' filesystem on a
host, which may result in a Denial of Service (DoS) to any
functionality that depends on that fileystem.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
*
Solaris 10 8/07 without patch 136839-01
*
Java Enterprise System (Java ES) 5 under Solaris 10
*
Solaris 8 with Sun Service Tag 1.0, 1.1, and 1.2, downloaded from the
Sun Download Center
*
Solaris 9 with Sun Service Tag 1.0, 1.1, and 1.2, downloaded from the
Sun Download Center
*
Solaris 10 with Sun Service Tag 1.0, 1.1, and 1.2, downloaded from the
Sun Download Center
x86 Platform
*
Solaris 10 8/07 without patch 136840-01
*
Java Enterprise System (Java ES) 5 under Solaris 10
*
Solaris 10 with Sun Service Tag 1.0, 1.1, and 1.2, downloaded from the
Sun Download Center
Enterprise Linux
*
Sun Service Tag RPM version 1.1 and 1.2, downloaded from the Sun
Download Center
This vulnerability can be exploited with or without the two Service Tag
network services (stlisten and stdiscover) being enabled.
Note 1: Only systems with the Sun Service Tag infrastructure installed
are vulnerable to this issue. To determine if it is installed,
execute the following command:
On the Solaris platform:
$ pkginfo SUNWservicetagr
On the Enterprise Linux platform:
$ rpm -q sun-servicetag
Note 2: The Service Tag product on the Windows platform is not
affected by this vulnerability.
3. Symptoms
If this issue is exploited to cause a Denial of Service (DoS) to
the system the /var filesystem may become full, causing
applications and services which depend on this filesystem to fail.
4. Workaround
There is no workaround for this issue. Please see the Resolution section
below.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
*
Solaris 10 8/07 or Java Enterprise System (Java ES) 5 under
Solaris 10 with patch 136839-01 or higher
*
For Solaris 8, 9, and 10 systems on which Sun Service Tag was manually
installed via a download from the Sun Download Center, version 1.1.3 or
higher should be retrieved via the "Download Service Tags" link at:
https://inventory.sun.com/inventory/
Then, the current packages should be removed:
# pkgrm SUNWstosreg SUNWservicetagu SUNWservicetagr
and finally the new packages should be installed, via pkgadd(1M),
as mentioned in the enclosed README from the Service Tag download.
x86 Platform
*
Solaris 10 8/07 or Java Enterprise System (Java ES) 5 under Solaris 10
with patch 136840-01 or higher

via a download from the Sun Download Center, version 1.1.3 or higher
should be retrieved via the "Download Service Tags" link at:
https://inventory.sun.com/inventory/
Then, the current packages should be removed:
# pkgrm SUNWstosreg SUNWservicetagu SUNWservicetagr
and finally the new packages should be installed, via pkgadd(1M),
as mentioned in the enclosed README from the Service Tag download.
Enterprise Linux platforms
The enterprise Linux version of Sun Service Tag, version 1.1.3 or
higher should be retrieved via the "Download Service Tags" link at:
