GEN:SID | 1:1987 |
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).
