Month of PHP Security Summary

it is 21th of May. The Month of PHP Security
(http://www.php-security.org) is still running and we have reached a
vulnerability count of 40 vulnerabilities, which is nearly as much as we
disclosed during the whole Month of PHP Bugs in 2007. However there are
11 more days until the end of May and therefore there are still plenty
of more vulnerabilities to come. Escpecially the amount of SQL injection
vulnerabilites in PHP applications will increase, because it is called
SQL injection marathon for a reason. And we also have several articles
and submissions left.
There have been some changes to the website that should make it easier
to read and we also added the possiblity to comment on bugs/entries/news
and articles.
For those that don't already know you can follow the Month of PHP
Security on Twitter, too. Just follow @mops_2010
Here is the summary of what happened during the last 10 days.
