In an email from Chris Shiflett this week to the PHP Security News mailing list, he talks about a new project that the PHPSec is launching - SecurityFocus Summaries.

Each of the summaries details vulnerabilities found in PHP applications throughout the week, including all of the ones mentioned on the PHPSec mailing list:

Daniel Convissor of the PHP Security Consortium has launched a new project to help security-conscious developers and users keep abreast of the latest vulnerabilities in PHP and in applications written in PHP.

Aggregated from the weekly SecurityFocus newsletters, the SecurityFocus Summaries are available online at: http://phpsec.org/projects/vulnerabilities/securityfocus.html

So, be sure to check out the past issues as well as keep up with the future postings to keep abreast of the latest happenings in the security of PHP applications... (and yes, there's even an XML feed you can subscribe to!)
