Description Vincent Danen 2012-03-15 19:00:00 UTC

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.
