Upgrade nginx to version 1.4.1 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-bounds Write. The ngx_http_parse_chunked function in http/ngx_http_parse.c in nginx 1.3.9 through 1.4.0 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a chunked Transfer-Encoding request with a large chunk size, which triggers an integer signedness error and a stack-based buffer overflow.
