Nginx 1.4.4 has been released on November 19th 2013, fixing a request line parsing vulnerability by Ivan Fratric of the Google Security Team (CVE-2013-4547). More info in the changelog.
As a consequence, Dotdeb’s packages of Nginx 1.4.4 are now available for both Debian 7.0 “Wheezy” and Debian 6.0 “Squeeze” (amd64/i386).
Reminder : Users of naxsi-ui should be aware that it has been deprecated in the upcoming Naxsi 0.53 and that it won’t be provided by Dotdeb starting with the next Nginx packages.
As usual, if you want to know which module has been included in each Nginx flavor, you just have to look at this document.
