RE: EEYE: Kerio Personal Firewall Multiple IP Options Denial of Service

["Marc Maiffret" <mmaiffret () eeye com>]

Tiny Personal Firewall 6.0 was tested immediately after we had discovered the Kerio bug and the issue did/does not 
exist in the current version of Tiny Personal Firewall 6.0. Only versions of Kerio Personal Firewall 4.0.0 - 4.1.1 are 
affected by the IP Options bug.

| Does anyone actually *knows* if KPF 2 and the "Tiny" versions 
| are vulnerable to this? Kerio's web page says:
| 
| "Affected products: Kerio Personal Firewall versions 4.0.0 thru 4.1.1"
| 
| This indicates that the error was introduced in version 4, 
| whereas Eeye says "4.1.1 and prior".
| 
| Has anyone seen exploits for this circulating?
| 
| TIA
