REDHAT-BUG-803856

First published: Thu Mar 15 2012(Updated: )

A flaw was reported [1] in nginx versions prior to 1.0.14 and 1.1.17 where contents of previously freed memory could be sent to a client if an upstream server returned a specially crafted HTTP response. This could potentially leak sensitive information to the HTTP client. This has been corrected upstream [2],[3] and a patch [4] is available for earlier versions of nginx.
