SA Document Body
A Security Vulnerability in the Sun Cluster Global File System (see
below for details)
On a Sun Cluster File System, one or both of the following issues may
1. An unprivileged local user may be able to read data from deleted
files owned by other users.
2. Data integrity issues may occur on certain applications.
2. Contributing Factors
These issues can occur in the following releases:
* Sun Cluster 3.1 (for Solaris 8) without patch 117950-18
* Sun Cluster 3.1 (for Solaris 9) without patch 117949-18
* Sun Cluster 3.1 (for Solaris 10) without patch 120500-02
* Sun Cluster 3.1 (for Solaris 9) without patch 117909-18
* Sun Cluster 3.1 (for Solaris 10) without patch 120501-02
Note: Sun Cluster 3.0 is not vulnerable to this issue.
The described issues only occur on global filesystems mounted on top
of ufs filesystems. These issues have not been seen on global
filesystems mounted on top of vxfs filesystems.
There are no reliable symptoms that would indicate issue 1 described
above has been exploited.
If issue 2 described above occurs, files in global filesystems may
contain garbage data. This may cause unpredictable results following
file read operations.
There is no workaround. Please see the "Resolution" section below.
This issue is addressed in the following releases:
* Sun Cluster 3.1 (for Solaris 8) with patch 117950-18 or later
* Sun Cluster 3.1 (for Solaris 9) with patch 117949-18 or later
* Sun Cluster 3.1 (for Solaris 10) with patch 120500-02 or later
* Sun Cluster 3.1 (for Solaris 9) with patch 117909-18 or later
* Sun Cluster 3.1 (for Solaris 10) with patch 120501-02 or later
