"The remote host is affected by the vulnerability described in GLSA-201203-22
(nginx: Multiple vulnerabilities)

    Multiple vulnerabilities have been found in nginx:
      The TLS protocol does not properly handle session renegotiation
        requests (CVE-2009-3555).
      The 'ngx_http_process_request_headers()' function in ngx_http_parse.c
        could cause a NULL pointer dereference (CVE-2009-3896).
      nginx does not properly sanitize user input for the the WebDAV COPY
        or MOVE methods (CVE-2009-3898).
      The 'ngx_resolver_copy()' function in ngx_resolver.c contains a
        boundary error which could cause a heap-based buffer overflow
        (CVE-2011-4315).
      nginx does not properly parse HTTP header responses which could
        expose sensitive information (CVE-2012-1180).
  
Impact :

    A remote attacker could possibly execute arbitrary code with the
      privileges of the nginx process, cause a Denial of Service condition,
      create or overwrite arbitrary files, or obtain sensitive information.
  
Workaround :

    There is no known workaround at this time."
