| Message | MISC xfs overflow attempt |
| Summary | This event is generated when an attempt is made to exploit a flaw in the X Windows Font Service.
|
| Impact | Arbitrary code execution. Denial of Service.
|
| Detailed Information | Certain versions of XFS distributed with Sun's Solaris are vulnerable to a remote buffer overflow. The Dispatch() routine within fs.auto does not provide adequate bounds-checking.
|
| Affected Systems | Sun Solaris 2.5.1 to 9 (Update 2)
|
| Attack Scenarios | An attacker must have access to tcp port 7100. The attacker can then either cause XFS to crash or run code as user "nobody".
|
| Ease of Attack | Difficult
|
| Corrective Action | Disable XFS in the inetd configuration file (normally /etc/inetd.conf under line fs.auto).
