January 12, The Register - (International) Frustrated bug hunters to
expose a flaw a day for a month. A Russian security firm has pledged to
release details of previously undisclosed flaws in enterprise
applications it has discovered every day for the remainder of January.
Intevydis intends to publish advisories on zero-day vulnerabilities in
products such as Zeus Web Server, MySQL, Lotus Domino and Informix and
Novell eDirectory between January 11 and February 1, a security blogger
reports. As an opener, Intevydis published a crash bug in
Sun Directory Server 7.0, along with exploit code. The final line-up of
zero-days is still being finalised, but the MySQL buffer overflows and IBM
DB2 root vulnerability flaws on the provisional menu sound much tastier than
Intevydis's somewhat bland opener. Advisories are due to be published on
the Intevydis blog here. Intevydis said it launched its campaign after
becoming more and more disillusioned with foot-dragging by vendors when
confronted by security flaws in their products. Only one software vendor,
Zeus, reportedly worked with Intevydis in developing a patch to be
released at the same time as an upcoming advisory from the Russian
security firm. Intevydis's stance is likely to reboot the long running
debate about the responsible disclosure of security vulnerabilities. An
entry on the Intevydis blog accuses software vendors of exploiting researchers
as unpaid lackeys. Source:

I search the archives for discussions on the performance implications of
Drop/Deny or Reject rules, but only found discussions of how much
information is revealed.

Is there any performance difference between a Drop/Deny or Reject rules?
IDK if it's relevant, but I'm using iptables. If there isn't performance
hit between the two rules, is there anything else that might steer me
towards picking one over the other?
