Title: cluster Multiple Insecure Temporary File Creation Vulnerabilities
Severity: MODERATE
Description:
The cluster program is a freely available application for creating clusters on Linux systems.
Multiple components of the application may allow attackers to create temporary files in an insecure manner. The following components are affected:
'CMAN'
'rgmanager'
'gfs2-utils'
An attacker with local access could potentially exploit these issues to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.
Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.
These issues affect versions of cluster prior to 2.03.09.
Affected Products:
- RedHat Enterprise Linux 5 server
- RedHat Enterprise Linux Desktop 5 client
- RedHat Enterprise Linux Desktop Workstation 5 client
- RedHat Fedora 9
- RedHat cluster2 2.03.07
- RedHat cluster2 2.03.08
