A security hole was discovered in the package mentioned above.

this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected as

1. Problem Description
The mount/umount command doesn't do proper bounds checking on user input.
2. Impact
If an attacker executes mount/umount with a long relative pathname, it
will overwrite dynamic allocated memory of the realpath function.
It is possible that an attacker could gain root privileges by modifying
the heap data, however we were not able to exploit it.
3. Solution
Update the package from our FTP server or remove the suid bits.
