A Security Vulnerability in the Sun Cluster Global File System (see below for details)

1. Impact

On a Sun Cluster File System, one or both of the following issues may occur:

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:

SPARC Platform

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

x86 Platform

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.

3. Symptoms

If issue 2 described above occurs, files in global filesystems may contain garbage data. This may cause unpredictable results following file read operations.
