Description Vincent Danen 2011-11-17 16:27:51 UTC
It was reported [1] that a heap overflow flaw in nginx's custom DNS resolver was corrected in upstream version 1.0.10 [2],[3].  This resolver is most commonly used with the proxy and fastcgi modules, which are not enabled by default.  As well, a malicious user would need to be in control of an upstream resolver host, or be able to brute-force the weakly-generated 16-bit transaction identifier, to exploit the flaw.
