Re: Transaction ID is just not enough (even if 100% "random") said by Alan Clegg :
If you have sufficient transaction ID randomness, then to a certain degree the source port randomness is just an academic bonus.
You sir, are completely incorrect. Completely ?
I will acknowledge that I overstated on source port randomness just being a bonus. Still, the most exploitable servers are those that are still using fixed source port queries, followed by the previous bind implementations that still had limited entropy for both the source port and transaction ID.
The servers being reported with "poor" source port randomness (ie, randomness within a fixed range) but "good" for transaction ID randomness are still better off than those servers out there still susceptible to »securitytracker.com/alerts/2007/···442.html . |
