nginx 1.0.13 Information Leak

Change Mirror Download
Hello,

The nginx team has released stable version 1.0.14, and development
version 1.1.17 of nginx web server, which include a fix for malformed
HTTP responses from upstream servers:

http://trac.nginx.org/nginx/changeset/4535/nginx
http://trac.nginx.org/nginx/changeset/4531/nginx
http://trac.nginx.org/nginx/changeset/4530/nginx

http://nginx.org/en/security_advisories.html

Without this fix contents of previously freed memory might be sent to
a client if an upstream server returned specially crafted response,
potentially resulting in sensitive information leak.

Patch which can be applied to the earlier versions of nginx is here:
http://nginx.org/download/patch.2012.memory.txt

Thanks to Matthew Daley for spotting this one.

-- nginx team
